1 E4 XLS+ Single Channel Pipettes

Rainin’s E4 XLS+ is a revolutionary electronic pipette fully laden with features and with a new graphical user interface that is extremely straightforward and intuitive in operation. The joystick control provides an easy to understand logic for setting operating modes and for aspiration and dispensing a variety of liquids. The pipette is designed for maximum comfort.

You can store your favorite protocols, configure the pipette set-up to your needs, and control access to pipette settings via passcode protection.

In models with the patented LTS

LiteTouch

Tip Ejection System, tip ejection forces are reduced by up to

85% in the single channel LTS models, and consistent sample pickup is easily attained across all channels in multichannel models, as well as tip ejection force reduction.

E4 XLS is available in single, multichannel and adjustable spacer versions.

All user settings and service settings are stored on nonvolatile memory and are protected even if the pipette is reset or in the unlikely case of a battery failure.

E4’s built-in Service GLP section help you track the pipette’s service records and intervals. E4 XLS models also contain an RFID tag (radio-frequency identification) for facilitating calibration management for all your pipette assets.

This manual describes features introduced with the

XLS+ model, firmware 1.4.

Volume Settings

Allow users to set the volume of sample to be aspirated. Minimum and maximum volumes are dependent on the

E4 XLS pipette model. The type of Volume Setting displayed depends on what options are turned on or off in the operational mode.

Single Volume . Allows one volume to be set and used for aspirate/dispense. When this setting

is active,

Volume

is displayed in the

Volume Setting

box. This is the default volume setting for all operational modes, and the only volume setting available in Basic Mode.

Fixed Volume . Allows one of 14 preset volumes to be selected from a volume table. This setting

is shown only when the Fixed Volume option is on. When this setting is active,

Fixed Vol X

is displayed in the volume setting box. For example,

Fixed Vol 3

indicates the volume shown is the third volume selection in the table.

Volume Sequencing . Allows up to 16 preset volumes to be selected for use in series from a

volume table. This setting is shown only when the Volume Sequencing option is on. When this setting is active,

Vol X of X

is displayed in the volume setting box. For example,

Vol 2 of 4

indicates the volume shown is the second of four volumes in the series selected in the table. The volume value and number will increment as each cycle completes.

Speed Settings

Allow users to set aspirate, dispense and mix speeds from 1 (slow) to 10 (fast). High speed settings are best for aqueous samples and lower speed settings are best for viscous, foaming, delicate or shear-sensitive samples.

The maximum speed settings for large-volume E4 XLS Basic Models are limited to prevent ‘fountaining’, or air intake, during aspiration. See Appendix A for a complete speed table.

Single Speed. Allows one speed value to be set which is used for both aspirate and dispense.

This is the only speed setting available in Basic Mode.

Multi-Speed. Allows aspirate, dispense and mix speed settings to be set individually. Displays

aspirate and dispense speeds (

Asp/Dsp Spd

) initially. During operation, the set value and current operation (

Asp Speed

,

Dsp Speed

or

Mix Speed

) will be shown in the settings box as each action is carried out.

Cycle Count

Cycle is complete aspiration and dispense followed by blowout. Displays the operational mode’s current cycle count, which increments after each cycle completes. Cycle count can be set to any value between 0 and 99,999. This setting is shown only when the Cycle Counter option is on.

Mix

Allows users to perform in-tip mixing after dispense. A mix volume, up to 99 automatic mix cycles or manual mixing can be selected. This setting is shown only when the Mix option is on.

Minimum and maximum volumes are dependent on the size of the E4 XLS pipette. When automatic mix cycles are used, the set volume and number of mix cycles (

Mix Cyc X

) are shown in the settings box. The cycle number will increment as each mix cycle completes until the set number of cycles is reached. When manual mixing is used, the set volume and

Mix Manual

are shown in the settings box.

Preset Selector

Allows user to select a Mode Preset file, if one or more has been saved. The display shows how many presets are available and which one is currently loaded (if any). Activating this setting box allows users to scroll through and select any available preset with the joystick.

1.6 Using the Pipette

1.6.1 Pipetting Guidelines

E4 XLS pipettes incorporate several features to enhance pipetting consistency. In addition, these guidelines should also be followed:

• Use a consistent immersion depth

• Pipette vertically or within 20 degrees of vertical

• Pre-rinse the tip twice by aspirating and dispensing sample before actual pickup

• Do not invert or lay the pipette flat with liquid in the tip

More information on Good Pipetting Technique, including a Lab Poster, can be found on the MT website: www.mt.com/rainin

1.6.2 Tip Selection and Mounting

Rainin pipettes and tips are designed together as a pipetting system. E4 XLS pipettes are calibrated with Rainin tips. Performance to published specifications can only be guaranteed when Rainin tips are used.

To mount a tip, press the E4 XLS shaft into the end of the tip with light force. With both LTS and traditional versions, the tip will seal properly on the shaft with minimal force — do not use more force than is required.

1.6.4 Sleep Mode and Power Shutdown

E4 XLS is equipped with display and sleep timeout features, both of which assist in conserving battery life -

Sleep Mode reduces power consumption by 98%. E4 XLS will automatically sleep after a set period.

-

Display Timeout

. Dims the intensity of the display after a user-specified period of inactivity. To wake E4 XLS

from a display timeout, press either soft key or move the joystick in any direction.

Note: The soft key or joystick action taken to exit a display timeout will return the E4 XLS to ready mode only.

The associated soft key function or joystick command will not initiate.

-

Sleep Timeout

. Powers the display off and puts the unit into low power state after a user-specified period of

inactivity. To wake E4 XLS from a sleep timeout, press either soft key. The pipette will initialize and show the splash screen momentarily before returning the display to the last screen accessed.

Refer to “Setup Mode“ in section 9 for information on how to change the time setting for these timeout features.

Shutdown

Besides Sleep mode, the E4 XLS can also shut down completely. The E4 XLS automatically shuts down after

16 hours of non-use. If you wish to shut it down earlier, push and hold both soft keys simultaneously. After 3 seconds, the units beeps twice and a warning screen notifies you that you are about to shut down the unit. Press

Select

RETURN

to exit Help and return to the previous screen.

1.6.6 Filter

5000 μL, 10 mL, and 20 mL pipettes use a filter in the end of the shaft. This helps prevent liquid from entering the shaft and contaminating the piston should the plunger snap up during aspiration. Using a filter is recommended when pipetting large volumes. The filter should be replaced if it gets wet.

Figure 17: Filter Orientation

The 5000 μL and 10 mL pipettes use the same fi lter, as shown in the diagram above:

5000 μL: small diameter into the shaft. 10 mL: large diameter into the shaft.

Filter part numbers are 6190-164

6190-165

1.10 Admin Mode

Overview

Admin Mode allows you to control access to pipette settings and to personalize pipette configuration. This mode can be a helpful GLP/GMP/GCP compliance tool to enhance adherence to lab protocols and to prevent unauthorized changes to pipette settings. Admin Mode can be a useful tool for all users to simplify the pipette configuration, or as a convenient way to save personalized settings with a shared instrument.

The Mode Access feature allows individual Modes to be

Unlocked (usable and modifiable), Locked (usable but non-modifiable) or Hidden (inaccessible).

Service related settings such as Date/Time and Alarms can be individually Locked to prevent changes to the settings.

The administrator can Passcode-protect access to

Admin mode, thus preventing unauthorized access to changing pipette settings.

The administrator can also save the entire Settings profile of the pipette as a User Preset, or restore the pipette to Factory settings.

Setting Mode Access

Use this feature to simplify and control the pipette configuration by altering the accessibility of individual modes.

Mode access can be: Unlocked (usable and modifiable), Locked (usable but non-modifiable) or Hidden (inaccessible). The settings and options of a locked mode can be viewed, but not modified. Locking SetUp mode will prevent unauthorized changes in Setup to pipette configuration. When it is locked, the Setup screens can also still be viewed, which can be helpful if the user wants to check how certain features are set, such as alarms.

This is not possible if Setup is Hidden.

Admin mode cannot be hidden or locked (but can be passcode protected, see section below).

A Locked Mode will have a padlock icon on the operating screen in the bottom left corner. A Mode can be locked with a Mode Preset already loaded, however other Mode Presets cannot be accessed.

25

26

Date/Time and Alarm Lock

Turn these locks on (Figure A) to prevent changes to the Date/Time and Alarm settings in Setup mode. Useful for GLP compliance when on-board service alarms are being used, but you want to leave the rest of the pipette configuration unlocked.

Lock All

Turn this function on (Figure A) to prevent changes to any setting outside of Admin Mode. Useful for SOP compliance and adherence when the pipette is utilized for repetitive procedures that do not vary often. Note: This will only prevent changes to settings-any Mode that is not hidden (see Mode Access above) can still be used. A padlock icon appears on the system icon display.

Passcode Feature

Use a passcode to prevent unauthorized access to the

Admin functions.

Setting or changing a Passcode

1. or SET on page 2 of Admin mode to enter a new passcode (Figure B). If a passcode is currently active, it will be overridden by the new one.

2. Select a passcode. Use , , or to highlight numbers, to select a number. Passcode must be four digits long. DONE when complete (Figure

F).

3. CONT to confirm your passcode.

F: Set Passcode

4. A new “Passcode Protection” field will appear beneath the “Set Passcode” field on page 2 of Admin mode showing “ON” status (Figure G). A key icon in the system icon display area also indicates that a passcode is currently active (Figure G).

H: Enter Passcode

5. The active passcode is always the last one that was confirmed.

6. MAIN to exit Admin mode and enable the passcode protection.

7. Please store your passcode where you and approved colleagues can access it!

Removing Passcode Protection from Admin Mode

1. In the “Passcode Protection” field, or ON to turn passcode OFF (Figure G).

2. CONT to confirm passcode removal.

G: Passcode ON

J: Passcode UNLOCK

Entering Admin Mode with Passcode Protection

After a passcode is set, re-entry into Admin mode requires entering the passcode (Figure H).

If you forget your passcode, select UNLOCK from the passcode screen and call technical support

(800-4-RAININ)in the USA or your local METTLER TOLEDO representative (Figure J).

User Preset Feature

A User Preset is a file that stores the entire settings profile of the pipette, including Admin mode, with two exceptions.

• User Presets do not include a passcode. The passcode setting is always the last active setting.

• User and Mode Presets (see Mode Presets Option section) are stored separately on the on-board micro-SD card. Mode Presets are therefore not linked to any User Preset.

User Presets can be helpful tools for storing different configurations of the pipette settings for distinct tasks.

Some tasks might require a more open configuration

(e.g. R&D) while others require a very restricted and more controlled configuration (e.g. manufacturing processes). Saving each configuration as a User Preset allows the user to quickly re-configure the pipette for different purposes.

1.15 Battery Charging

Unlike other battery types, the Li-Ion battery in E4 has no “memory effect” and does not need to be fully discharged.Pipettes can be charged using the Wall Power Supply, the optional Rapid Charge Stand or with a PC using the optional USB cable.

The battery charge indicator in the top right corner of the display will change as the unit is charging. After 15 minutes, the pipette will have enough charge for a few hours of pipetting, and a full charge will be obtained after approximately 90 minutes and will provide up to 3000 full-stroke cycles (fewer in large-volume models).

When charging is complete, the battery charge indicator will be solid green, indicating a full battery. As the battery depletes with use, the green bar will drop accordingly.

Wall Power Supply

To install the universal Wall Power Supply and charge E4, connect the power cord to a power outlet. Connect the other end of the cord to the Micro USB port located on the top of the unit. The pipette can be operated while connected to the Wall

Power Supply cord.

Figure 26: Operating the pipette while connected to E4-WPS Wall Power Supply

Rapid Charge Stand

To use, connect the universal Rapid Charge Stand power cord to a power outlet and connect the other end of the cord to the power socket on the back of the Rapid Charge Stand. For convenience, you can dress the cable along one of the vertical support legs using the channels provided. See Figure 27 B.

Figure 27: A: E4-RCS holding E4 XLS + pipettes. B: Back of E4-RCS showing power cord connected and dresses along support leg

The E4-RCS Rapid Charge Stand will charge three E4 XLS+ pipettes simultaneously in about 90 minutes. Charging contacts mate with contacts under the pipette head.

Rainin recommends storing E4 XLS+ on the stand when not in use. This practice will provide a safe storage place, and the pipette will always be fully charged.

52

USB Cable

To charge E4 XLS with a PC using the optional USB cable, connect the cable’s USB connector to a computer USB port. Connect the other end of the cable to the USB outlet located on the top of E4 XLS. Rainin does not recommend operating E4 XLS when the pipette is connected to a computer for charging.

(Note that charging E4 XLS with a PC will take approximately 2–3 times longer than using the Wall Power Supply or the Rapid Charge Stand.)

Electrical Specifications

This device is intended for use only with Rainin power sources with the part numbers listed below.

No other power sources may be used with this device.

It is important that the Wall Power Supply and Rapid Charge Stand can quickly be disconnected from AC power, in case a hazard arises.

1.16 Replacing the Battery

E4 XLS user settings are retained if the battery is removed or replaced.

1. Open the battery compartment by sliding the compartment door open.

2. Remove the old battery by sliding it out.

3. Align the replacement battery connector plug with the socket in the battery compartment as shown in Figure

28. Slide the battery into place. Once the battery is installed properly, the pipette will turn on automatically, initialize and display the start-up screen.

4. Replace the battery compartment door.

Figure 28: Replacing the Battery

The battery life is dependent on such factors as:

- Pipette volume range

- Full-range or part-range pipetting

- Multidispensing

- Display brightness and display timeout settings

1.17 Storage

After use, store the pipette in a clean safe place. E4 XLS+ is a precision instrument and should be treated with the level of care appropriate for laboratory instrumentation.

Rainin recommends storing E4 XLS on the Rapid Charge Stand if one is available. If not, three hangers are available to hold E4 XLS conveniently when not in use:

- CR-7: Free-standing carousel that holds three pipettes.

- HU-M3: Set of three individual magnetic Hang-Ups

for mounting on ferrous surfaces.

- HU-S3: Three Hang-Ups attached to a clamp that fits onto a shelf.

Note: All of the hangers listed above require a HU-A3 Adapter.

1.18 Tip Ejector Arm Removal

Four types of tip ejector are used and all types can be removed with minimum effort – do not use force.

For models up to 2000 μL

Metal tip ejector: press in the quick-release tabs on the ejector arm and pull the arm down.

Plastic tip ejector: grasp fi rmly on the ejector arm and pull down.

For 5000 μL & 10 mL models: grasp the top of the ejector arm and pull out then down.

For the 20 mL model: pull off the lower part of the ejector arm; the upper part stays in place. (Replace by align-

ing the rod with the hole in the upper part and pressing fi rmly.)

≤ 2000 μL metal ≤ 2000 μL plastic 5000 μL -10 mL 20 mL

Figure 29: Removing the Tip Ejector

To replace the ejector arm (except 20 mL described above), insert the shaft through the large opening, align the top of the ejector arm with the tip ejector push-rod, and push the ejector arm fi rmly until it is securely in place.

1.19 Care and Maintenance

E4 XLS pipettes are sophisticated lab instruments and should be treated with appropriate care. These pipettes should provide years of trouble-free service if the operating recommendations in this manual are followed.

The most important factor in taking proper care of E4 XLS is to keep the mechanism dry and clean. The following simple rules should be strictly observed:

1. Never allow liquid to enter the shaft where it can contact the piston or seal.

1. Never allow liquid to enter the electronics, including the display, soft keys and joystick.

2. Never pick up liquid without a tip attached.

3. Never invert the pipette or lay it on its side with liquid in the tip. Always hold E4 XLS upright and store upright if possible. The Rapid Charge Stand holds three E4 XLS pipettes and charges them simultaneously.

4. Never use aggressive solvents to clean E4 XLS. It is best use a lint-free wipe dampened with water with dilute mild detergent, if needed, to clean the instrument. Be sure to keep the display, soft keys and joystick dry.

5. Never attempt to recharge E4 XLS with a device other than the Rainin E4-WPS Wall Power Supply, the E4-RCS

Rapid Charge Stand or the E4-USB cable. Severe damage to the internal electronics will result.

Sample contamination of the shaft, seals or piston can cause rough, sticky plunger movement. Eventually deposits on the piston can cause the seal to tear, leading to inaccurate results. Best practice for pipette maintenance is to regularly clean the pipette liquid end with the following procedure:

1. Remove tip ejector arm (See Tip ejector arm removal Figure 29).

2. On pipettes up to 1000 μL unscrew the shaft coupling nut and remove shaft. For 2000 μL unscrew the shaft.

For pipettes >2000 μL unscrew the lower part of the shaft.

3. When you remove the piston assembly, note the order and placement of the seals, retainers, springs and orings on the piston assembly. XLS+ seals for models 100-2000 μL are asymmetrical and must be inserted in the correct orientation (See figure 30 A and B). XLS+ seals for models 2-20 μL are symmetrical and can be used in either orientation.

Figure 30C: Using the large end of a tip to remove 1000 or 2000 μL XLS+ seal from the shaft

4. XLS+ seal sizes 1000-2000 μL may remain inside the shaft when you remove the piston assembly; this is normal for this design. The seals may be removed from the shaft by inserting the large end of a tip into the shaft (See Figure 30 C) and hooking the seal over it.

5. To inspect and clean seals sized 100-300 μL, remove them gently from their retainers by pushing them out from the back side, preferably with a non-sharp object like a pipette tip.

6. Inspect the seals, retainers, o-rings, shaft and piston for contamination. Clean with a lint- free cloth with either distilled water or isopropyl alcohol. Apply grease (part number 6200-524, 17014531) sparingly by gently rubbing the seal or o-ring between the thumb and index finger, ideally using a clean powder-free examination glove. Apply a small amount of grease on the piston as well.

Reassemble in the correct order and orientation.

7. If piston corrosion or staining is evident do not use the pipette and have a METTLER TOLEDO Service representative assist with replacement of the piston.

8. The shaft, tip ejector and handle may also be cleaned using a damp cloth with distilled water, 10% bleach solution, isopropyl alcohol, or any commercially available instrument decontamination solution. Be sure to rinse off the cleaning agent with distilled water

1.20 Autoclaving

Autoclaving of your pipettes to perform sterilization may be performed at 121ºC, at 1 Bar, for 15-20 minutes, with the following restrictions and guidelines.

Do not autoclave the entire pipette or any part not specifically identified in the table below.

Shaft, tip ejector, piston assembly, spring, seal, and seal retainer

None

The entire liquid end of E4 XLS+ single channel pipettes may be removed and placed into the autoclave without disassembling individual parts. The liquid end includes the following: Shaft, tip ejector, piston assembly (with spring), seal and seal retainer. If you have upgraded the seals of an older E4 XLS to the new XLS+ seals (see section 1.21), you can now autoclave the entire liquid end of your pipette. If you are unsure of your model type see section 1.21.

If autoclaving more than one unit together, take care to reassemble your pipettes with all of their original parts.

If you clean the XLS+ piston and seals before autoclaving then be sure to re-grease them afterwards (see Care and Maintenance).

See Care and Maintenance and Replacement Parts sections for more details on disassembling pipettes, and how to identify the different parts.

-

1.21 Upgrading your Liquid End to XLS+

The XLS+ single channel line of pipettes is distinguished from earlier models by having a new lower stiction sealing system, a completely autoclaveable liquid end, and a durable, corrosion-free plastic tip ejector.

If you have a single channel E4 XLS pipette in the 2-2000 μL range, you can upgrade your liquid end to experience the superior benefits of XLS+.

You can differentiate an XLS+ pipette from the earlier XLS version in the following ways: an original XLS+ pipette will have a serial number beginning with C14 (or higher) but not A14 or B14. Also the RAININ logo on the silver badge is colored blue. All the XLS+ seals are black, and no o-rings are used, while the XLS seals are white, and o-rings sit below the seal on the piston.

55

You can upgrade your liquid end by ordering the seal replacement kit (see Replacement Parts). The new XLS+ seals require grease part# 6200-524 17014531 (see Care and Mainte nance). For the 1000 and 2000 μL models, replacing the seal retainer requires specialized tools and handling to avoid damage to the piston. Please call technical support (800-543-4030 in the USA) or your local METTLER TOLEDO service provider.

1.22 Troubleshooting

Problem

Leaks, inaccuracy

Possible Cause

Loose shaft

Rough, jerky, or sticky plunger movement

Suggested Remedy

Tighten coupling nut by hand.

Worn seal for pipette volumes ≤ 2000 μL Replace seal

Worn o-ring or insuffi cient grease seal for pipette volumes 5000 μL, 10mL, 20 mL

Replace o-ring and apply small amount of grease.

Cracked or split shaft.

Contamination inside mechanism.

Insuffi cient grease

Replace shaft. Check piston is not bent. If bent, call Rainin service for a new piston.

Call 800-543-4030 in the US.

Remove tip ejector arm, remove shaft and check piston and seal clean as described in

Care and Maintenance section. If piston is permanently corroded or stained, call Rainin service for a new piston. Call 800-543-4030 in the US.

Apply grease sparingly to seal or o-ring

When removing the shaft from the pipette body, make sure the spring, seal and o-ring do not detach from the piston, especially on smaller models. Be careful not to bend the piston on these small models. Recalibration of the pipette is only required when the piston is replaced.

Acids and Corrosives

Extensive contact with corrosive fumes may result in premature seal wear and damage to the piston. Exposure of the internal components to corrosive aerosols and fumes may be reduced by using Rainin tips with aerosol barrier filters. After using concentrated acids or corrosive solutions, disassemble E4 XLS and inspect and clean the piston assembly, shaft and seal/o-ring with distilled water. Use extreme care on the 10 μL models to avoid damaging the small diameter piston, or losing small items such as seals. Dry all components thoroughly and reassemble.

Warning Messages

E4 XLS + monitors itself to inform you of important issues such as battery levels, USB connection, charge stand connection, factory reset, real time clock status and more. Any changes to these variables that could affect your operation of the pipette will be reported as a Warning message. Some warnings require action, such as recharging the unit or resetting the clock, while others are informational only (“Memory Clear” after factory reset). To exit any warning message, press the left softkey (CONT). If a warning message is displayed during the E4 XLS power up sequence that cannot be reset, note the error number and contact Tech Support at 800-543-4030 in the US. In other countries contact METTLER TOLEDO or your distributor.

Error Messages

E4 XLS+ is a sophisticated product that is dependent on a complex mix of electronic hardware and software components. In any complex system such as this, faults may occasionally occur. These are usually due to unexpected software conditions (invalid data, conflicting settings, etc.) or hardware related failures (invalid or no

56

response). An Error message informs you that a fault has been detected. Press the left softkey (CONT) and the unit will reset itself while performing a diagnostic test. Most of the time, the unit will fix itself, and pipetting can be resumed normally. If the error messages continue, please cease pipetting, note the error code and message, and call Tech Support at 800-543-4030 in the US. In other countries contact METTLER TOLEDO or your distributor.

1.23 Micro-SD Card Management and Firmware Upgrades

Introduction

With the release of the Rainin E4 firmware V 1.4 the included micro-SD card will add new functionality to the pipette. In previous firmware versions only PureSpeed™ protocols used the micro-SD card. Now the new ‘Preset’ features will also use the SD card.

Inserting and removing the SD card

New pipettes with version 1.4 firmware will come with a Rainin micro-SD Card preinstalled. To upgrade older pipettes, a Rainin micro-SD Card can be purchased from Rainin or an authorized distributor. Please see below for ordering information.

The micro-SD card is located in a small slot on the left side beneath the battery compartment (as seen from the back of the pipette). A label under the battery door identifies the location of the SD-card. See A below.

A

To change or insert a new SD card, remove the battery compartment door and the battery. Insert the card with minimal force into the SD-card slot as shown in the figure with the metal contacts facing down. Push the card with your fingernail or a small, blunt non-conductive object (e.g. an unused pipette tip) into the slot until a slight “click“ can be felt or heard.

To remove the card, use a similar tool: Push in the card until a click is heard, then release the card and the spring in the card socket will push the card out a little bit and it can be removed. Do not touch the metal contacts of the card. Store in a clean, dry and cool environment.

If the card is inserted or removed while the pipette is powered on, a message will appear on the screen and inform about the card insertion or removal and the pipette will restart.

After the SD-card is inserted properly and the pipette powered on, an SD card system icon is displayed and the

SD card functions like “Presets“ and “PureSpeed“ become available.

Model-specific Presets and Interchanging micro-SD cards

Presets are model-specific. Presets stored on micro-SD cards are only interchangeable between models with the same volume e.g. 200 μL single, 8 and 12 channel pipettes. If the SD-card is transferred to a pipette with a different volume, existing saved presets will not show up but new presets can be saved for the different model.

Troubleshooting

If you get an SD card error message, please confirm that the card is properly inserted into the pipette and is clean and undamaged. If the error message persists, or preset files are not readable, please contact Rainin

Tech Support at [email protected].

57

58

Ordering SD cards and Upgrading older E4 models

To order new micro-SD cards, use part# 17012587, Model PT-E4-SD. The new E4 functions require at least firmware version 1.2 for PureSpeed™ and version 1.4 for Mode Presets and Admin mode. If you have an E4 unit with older firmware, please contact your local MT representative to upgrade your firmware.

1.24 Service, Calibration and Repair

It is recommended to use only genuine Rainin replacement parts such as seals, o-rings, and shafts. It is NOT necessary to recalibrate the pipette after changing the seal, o-ring, or shaft. Recalibration of the pipette is only necessary when the piston is replaced, and should be done only by qualified factory-trained personnel in a

Rainin approved facility.

For pipettes under warranty, please note that the warranty will be voided if the pipette has been damaged as a result of physical or chemical abuse, or if the pipette has been repaired or recalibrated by any service facility which is not authorized by Rainin. In the US, call 800-543-4030 for service. Service is also available outside the US. See www.mt.com/rainin for more information.

2 RFID (Radio Frequency Identification Device)

2.1 Description and Operation

All E4 XLS models incorporate a passive RFID tag in the finger-hook. The tag contains unique information about the pipette including model type, serial number, RFID UID and service calibration information. The RFID tag can be wirelessly linked with the optional reader and software to facilitate querying calibration tracking and service reminders. The RFID tag is of negligible weight and has no effect on precision or accuracy. It operates only when read by an RFID reader and the associated software.

Optional Rainin RFID Reader

Rainin recommends the Rainin RFID Reader which interfaces with a PC USB port, and does not recommend any other RFID readers. Using the Rainin RFID Reader, information can be written to the pipette’s RFID tag in the same consistent way as it is read from the RFID tag. The Rainin RFID Reader requires LabX

Direct Pipette-Scan

Software for read/write capability. The estimated range of operation of the RFID reader is up to 5 cm.

Scan software. Once the Rainin RFID Reader is connected via USB to a PC and the software is configured and running, operation is simple.

Place the head of the pipette over the Rainin RFID reader in the position shown in 30. Hold the pipette steady for a few seconds to allow the pipette information stored in the RFID tag to be scanned and read into the software.

Pipette RFID-Tag Read-Only Fields

The software will display the read-only data fields programmed into each pipette’s RFID tag before it leaves the factory ( 1). These fields can ONLY be modified by Rainin at the time of manufacture or when sent in for service.

Read-only fields include: RFID UID, Model Number, Serial Number, Factory

Figure 33: Rainin RFID Reader

Date, Last Service Date and Next Service date. For QC or workflow purposes, multiple RFID enabled pipettes can be scanned sequentially.

Figure 34: Read-Only Pipette Data in Lab X Direct Pipette-Scan Software: Before Scan (top) and After Scan (bottom)

Writing Data to Custom Fields in the RFID Tag

In addition to read-only fields, several writable fields are available on the RFID tag. These can be customized and/or standardized to suit the needs of an individual user or laboratory.

Custom writing operations require both the Rainin RFID Reader and the LabX Direct Pipette-Scan software.

Please refer to the software help file for complete instructions.

RFID/LabX Direct Pipette-Scan Software Benefits

- The flexibility of the LabX Direct Pipette-Scan software assists users in customizing individual workflows

- Entire departments can standardize both workflow and calibration checks when using the E4 XLS pipettes,

Rainin RFID Reader and LabX Direct Pipette-Scan software as a complete system

61

62

- The system simplifies the Quality Compliance process by shortening the calibration check cycle, allowing pipettes to be returned to active lab use faster

- Custom fields can be configured and written to the RFID tag and advanced workflows can be defined for custom settings

- Informationwithin the tag can be exported to common formats, such as Excel® and Word® as well as Text., to facilitate records-keeping

What RFID Does Not Do

- RFID does not protect against misplacement, theft, or provide a pipette’s location

- RFID does not protect against erroneous data input

- RFID does not replace calibration stickers for businesses or displace QC professionals

- RFID does not validate laboratory workflows. The validation of the workflow and 21CFR Part 11 regulatory compliance remains the responsibility of the customer.

3 E4 XLS+ Multichannel Pipettes

3.1 Description and Operation

Introduction

E4 XLS+ multichannel pipettes are based on the E4 XLS single-channel pipette and use the patented LTS LiteTouch Tip Ejection System. Multichannel

E4 XLS+ is available in 8-channel and 12-channel versions. An 8-channel version is shown in 2.

The 8- and 12-channel models are available in 6 volume ranges:

0.5–10 μL

2–20 μL

5–50 μL

20–200 μL

20–300 μL

100–1200 μL

Tip Selection

E4 XLS+ multichannel pipettes use Rainin LTS tips.

- Use 20 μL LTS tips with the following E4 XLS+ models: E8-10XLS+,

E8-20XLS+, E8/12-10XLS+ and E12-20XLS+.

- Use 250 μL LTS tips with the following models: E8-50XLS+, E12-50XLS+,

E8-200XLS+, and E12-200XLS+.

- Use 300 μL LTS tips with E8-300XLS+ and E12-300XLS+

- 1200 μL LTS tips are recommended for E8-1200XLS+ and E12-1200XLS+.

Non-filter 1000 μL LTS tips can also be used as they will pick up 1200 μL.

LTS tips have a cylindrical cross-section with a well-defined seal ring, thin wall, and positive stop. They seal properly on the shaft and cannot be jammed or forced too far onto the shaft nozzles, and provide absolutely consistent sample pickup across all channels.

Figure 35: E4 XLS+ MultiChannel Pipette

Mounting LTS Tips

Mounting racked LTS tips on L8 and L12 pipettes is simple.

1. Align the shaft nozzles into the row of tips, holding the pipette at an angle ( 3 left).

2. Position the pipette upright and press the nozzles into the tips until the “positive stop” is reached

( 3 right).

The tips are now mounted with proper sealing. There is no need to hand-tighten, use heavy pressure, or rock the nozzles onto the tips to obtain a good seal.

E8-200XLS+, E12-200XLS+, E8-300XLS+, E12-300XLS+,

E8-1200XLS+, E12-1200XLS+

Operate the pipette within 20 degrees of vertical.

Immersion Depth

2-3 mm

3-6 mm

Tip Ejection

Simply press on the tip ejector button. All tips are ejected cleanly with minimal pressure on the thumb because of the progressive eject design built in to the liquid end manifold.

Positioning the Liquid End Manifold

The liquid end manifold can be rotated to any angle for convenience when filling plates. There is no need to loosen the coupling nut.

Note: Unique tips for 1200 μL models

The RT-L1200 and RT-L1200S tips are specifically designed for use with 1200 μL models in MULTIDISPENSE mode.

The unique design of these tips prevents drop formation and eliminates the need for touch-off between dispenses in

MULTI DISPENSE mode.

The RT-L1200F aerosol-resistant tip allows a full 1200 μL to be aspirated under the filter. However, fluid dynamics dictate that touch-off may be required when multidispensing.

4 E4 XLS Adjustable Spacer Pipette

4.1 Description and Operation

Introduction

E4 XLS Adjustable-Spacer multichannel pipettes are based on E4 XLS single-channel models, and operate in the same way. Two versions of the E4 XLS Adjustable-Spacer pipette are available: 6-channel (LA6) and 8-channel (LA8). Nozzle spacing adjustment ranges are listed below:

6-channel: 9 mm to approximately 19 mm

8-channel: 9 mm to approximately 14 mm

6-channel versions are available in the following volume ranges:

20–300 μL

100–1200 μL

8-channel versions are available in the following volume ranges:

5–50 μL

20–300 μL

100–1200 μL

Spacing Controls and Indicators

Nozzle spacing is changed with the use of two knurled knobs on either end of the liquid end manifold: the SPACING ADJUSTMENT knob and the LIMITER knob, shown in Figure 34.

Figure 34: E4 XLS Adjustable Spacer

A: SPACING ADJUSTMENT

B: LIMITER

The LIMITER knob, which is marked with the nozzle spacing range, sets the desired maximum spacing within the pipette’s spacing range.

A vertical arrow at the top of the knob on the liquid end manifold is the set point, shown in 35.

SET POINT

When the maximum spacing with the LIMITER knob has been set, turn the SPACING adjustment knob to open the nozzle spacing to the set value. A scale on the liquid end manifold gives a visual reference of the set spacing. Simply line up the leftmost nozzle with the scale on the manifold.

Figure 35: Limiter Set Point

The full range of adjustment for the 8-channel version is shown in 6. Nozzles are set to 9 mm spacing on the left, and 14 mm spacing on the right.

65

Figure 36: Nozzles: Minimum Spacing (left) and Maximum Spacing (right)

Tip Selection

E4 XLS multichannel pipettes use Rainin LTS tips. Use 250 μL LTS tips with the EA-50XLS. Use 300 μL LTS tips with the EA6-300XLS and EA8-300XLS. 1200 μL LTS tips are recommended for the EA6-1200XLS and EA8-

1200XLS. Non-filter 1000 μL LTS tips can also be used as they will pick up 1200 μL.

LTS tips have a cylindrical cross-section with a well-defined seal ring, thin wall, and positive stop. They seal properly on the LTS nozzles and cannot be jammed or forced too far onto the nozzles.

Mounting LTS Tips

Mounting racked LTS tips on Adjustable Spacer XLS pipettes is simple.

1. Set the nozzle spacing to 9 mm (same as the spacing for racked tips) by rotating the dark grey SPACING AD-

JUSTMENT knob fully clockwise.

2. Align the nozzles into the row of tips, holding the pipette at a slight angle ( 7 left).

3. Rotate the pipette upright and press the nozzles into the tips until the “positive stop” is reached.

The tips are now mounted with proper sealing. There is no need to hand-tighten, use heavy pressure, or rock the nozzles onto the tips to obtain a good seal. Withdraw the tips from the tip rack ( 7 right).

66

Figure 37: Mounting LTS Tips

Setting the Nozzle Spacing

With tips mounted on the nozzles, and before aspirating sample:

- If the spacing for the receiving wells or test-tube block is known, set this value on the LIMITER knob.

- If the spacing is not known, hold the pipette so that the tip ends are above the centers of the wells or test-tube block into which sample will be dispensed. Look at the scale on the liquid end manifold, and note where the marked nozzle aligns. Set this value on the LIMITER knob.

- If the spacing is over-extended, simply click the LIMITER knob to smaller values, stopping when the tip ends are aligned over the centers of the wells/test tubes.

Once the LIMITER knob has been set, spacing the nozzles properly is simple:

1. Aspirate the sample(s).

2. Set the nozzle spacing by moving the SPACING ADJUSTMENT knob until it stops at the value set by the LIM-

ITER knob.

3. Dispense into the wells or test-tube block.

If you wish to reset the pipette back to factory settings, open the battery door. Using a clean pipette tip, gently press and hold the reset button (see illustration below) for about 7 seconds. The unit will beep, a splash screen will appear, and a “Memory Clear” warning will be displayed. Press the left softkey to continue. This reset will NOT remove service data from the pipette, or presets, which are stored on the micro-SD card.

RESET BUTTON

Figure 38: Resetting E4 XLS

The real-time clock, which keeps track of time and date, requires a continuous source of power. If the main

Li-Ion battery fails or is removed, and no external power source is applied (such as wall power or rapid charge stand) the clock runs off a back-up coin cell battery. This battery will keep the clock running for about 90-120 days. If the coin cell battery drains completely, a notice will remind you to reset the time and date after power is restored to the unit. A new coin cell battery will be needed to provide back-up power for the clock if desired. The

E4 uses one standard CR1220 lithium ion coin cell battery, which can be purchased at any consumer electronic store. For more information, please contact Technical Support at 800-543-4030 in the US, or your METTLER

TOLEDO office or distributor outside the US.
