Operation
Attach the tips:
When loading tip(s), press the pipette into the appropriate GripTip(s) until you hear and
“feel” a click indicating that a seal has been achieved. Once you feel the click, stop
applying pressure. When loading GripTip pipette tips using a multichannel pipette, slowly
rock the pipette from one side to the other side to ensure the proper seal is achieved.
Discard your used tips:
If liquid is in the tips, empty them by pressing the Purge Button (6). Tips are easily
removed by pressing the Tip Ejector (8).

Blowout modes
During the last dispense of a program, a blowout is performed automatically. Liquid may
be aspirated back into the tips when the pistons move back to the home position, a
process called blowin. There are two ways to perform the blowin:
• Automatic blowout: Pressing (and releasing) the Run Key starts the dispense with
blowout and automatic blowin. You can choose a timed delay between the blowout and
the blowin, see “Pipetting - Delayed blowin” under “3.4.1 Preferences” on page 16.
• Two-step blowout: Perform a two-step blowout to manually delay the blowin:
- Press and hold the Run Key to start dispense with blowout.
- Remove the tips from the target vessel.
- Release the Run Key to start blowin.

Operation
Recommendations for pipetting
INTEGRA Biosciences recommends the following techniques for enhancing pipetting
results. These techniques are consistent with ISO standard 8655-2.
• It is best to immerse the GripTips just enough in liquid (2-3 mm) to allow the desired
volume to be aspirated.
• Always prewet GripTips. After loading tips onto your pipette, aspirate and dispense the
full volume 2-3 times to coat the inside of pipet tips. Pre-wetting ensures that the liquid
and air inside the tips are at equal temperature and the dead air space is humidified.
• VIAFLO II Electronic Pipettes is an air displacement pipette. To properly dispense
liquids, ensure that the pipette tip is at a 0-30° angle against the wall of the container or
well. After dispense you must touch GripTips against wall or dip them into the liquid
after a dispense. This process is referred to as “touching off” or “tip touch” and prevents
liquid from clinging to the pipette tips.
• In programs such as Repeat Dispense, a first and last dispense can be programmed.
These two dispenses are not used and are dispensed into the waste as they contain the
accumulated pipetting errors. Using a first and last dispense is recommended if
accuracy and precision are of high importance.
• Viscous samples should be aspirated and dispensed at the slowest speeds to ensure
accurate pipetting. In addition, the pipetting mode “Reverse pipet” can be used to
optimize pipetting results with viscous samples.
• For pipetting liquids with high vapor pressures (such as methanol or ethanol), use
relatively fast pipetting speeds and avoid prolonged pauses after aspiration.
• Calibrate based on fluid type. VIAFLO II Electronic Pipettes is tested and calibrated at
the factory for use with distilled water at room temperature. It may be necessary to recalibrate your VIAFLO II Electronic Pipettes if the liquid to be used has different physical properties (specific gravity and vapor pressure) than water. Calibration mode can be
accessed in the Toolbox menu.
WARNING
Avoid pipetting for extended periods. To minimize the risk of repetitive strain
injury, include pauses of several minutes.

Servicing
6.3.1
Shipping to INTEGRA Biosciences
For any service or repairs, please contact your local service technician.
WARNING
If working with infectious materials, e. g. human pathogens, VIAFLO II
pipettes need to be decontaminated before sending them to service and the
declaration on the absence of health hazards must be signed. This is
necessary to protect service personnel.
6.3.2
Changing O-rings of tip fittings
300 µl, 1250 µl and 5000 µl VIAFLO II pipettes feature tip fittings with red O-rings. This Oring is used to seal against the inside wall of GripTips and serve to reduce the required tip
loading and ejecting forces.
44
INTEGRA Biosciences AG
VIAFLO II Pipettes – Operating instructions V01
Maintenance
O-rings are made of durable silicone. If necessary, e.g. in case of a leakage due to
damaged O-ring, you can replace these O-rings. A set of spare O-rings and an O-ring
removal tool are included with the large volume multi-channel pipettes and can be ordered
separately, see “8 Accessories” on page 59.
WARNING
Avoid mechanical damage of the tip fittings.
For 300 µl or 1250 µl pipettes choose the side of the O-ring removal
tool corresponding to the size of the pipette cylinder (300 µl or
1250 µl). Slide the O-Ring removal tool sidewards onto the tip fitting
until the O-ring (a) builds a loop. Cut the O-ring with a fine scissor
and remove it.
a
For 5000 µl pipettes use forceps to remove the O-ring.
b
Slide a new O-ring over the tip fitting (b).
6.3.3
Lubrication
The internal seals and O-rings are subject of very slow wear out. An undamaged thin
lubricant film is important to keep the seals tight. The lubricant recommended depends on
the VIAFLO II pipette size, see “8.2 Consumables” on page 59:
Single channel 12.5 µl, 125 µl, 300 µl:
Use Fluorocarbon Gel (#100-00136-50) to lightly lubricate the
piston (a) without components slided onto. Put a drop of grease
onto your fingers, lubricate the black O-ring (b) at slide it over the
white seal (c).

Calibration
The VIAFLO II pipettes are factory tested and calibrated under environmentally controlled
conditions using a gravimetric procedure in accordance with ISO 8655 standards. For the
accuracy and precision specifications, see “7.5 Pipette Specifications” on page 56.
Several conditions that would require recalibration of your pipette include a desire to:
• Optimize your pipette’s accuracy at a specific volume using aqueous liquid.
• Enable accurate displacement of non-aqueous based liquids (with different specific
gravities than water).
• Enhance accuracy when pipetting heated or cooled liquids.
For information regarding calibration service, please contact your local dealer.

Definitions
Blow-out: Discharges any residual liquid from the tip.
Blow-in: After the blow-out, the piston moves back into home position. This causes a
slight intake of air (or liquid if tips remain in the liquid).
Two step blow-out: To avoid an early blow-in, keep the run button pressed while
dispensing, remove the tips from liquid and then release the run button.
Pre-wet: The action of pre-coating the inside of the liquid contacting parts with a thin film
of the same liquid. Additionally, it equilibrates humidity of the air space inside tip and the
pipette.
Touch off: Touching the pipette tip against the surface liquid or side of well-plate to
release any sample liquids that might be on the end of the pipette tip.

6.4.3
Maintenance
Test Conditions and Environment
Tests and calibrations should be performed in conditions and environment according to
ISO 8655-6 standard.
• Temperature needs to be between 18–25 °C and remain constant (±0.5 °C) throughout the calibration.
• Optimal relative humidity of the environment is >50% and around the dispensing position 80%.
• GripTips, pipettes and distilled water need to be in the calibration laboratory for at
least 2 hours prior to calibration to reach temperature equilibrium with the environment.
• The balance must be validated using reference weights before and after a measuring
series. A low and high volume weight should be used. E.g.:
100 g (Mettler Toledo, #11119250)
10 g (Mettler Toledo, #11119220)
1 g (Mettler Toledo, #11119190)
10 mg (Mettler Toledo, #11119130)
CAUTION
Always use new, pre-wetted GripTips for leak test and calibration.
6.4.4
Pre-wetting of tips
Pre-wet new GripTips three times prior to starting tests and calibrations. This is required
every time a tip is changed.
1) Attach a new unused GripTip which correspond to the volume range of the pipette
directly from the rack without touching the tip by hand.
2) Use a separate waste container for pre-wet dispenses.
3) In the Pipet mode, program the pipette to aspirate full volume. Set aspirating speed at
6. Aspirate by pressing the Run Key.
4) Dispense: Keep the Run Key pressed until all liquid is expelled, remove the tip from
the liquid and then release the Run Key to perform a two-step blowout, see “4.3.2
Blowout modes” on page 21.

VIAFLO II Pipettes – Operating instructions V01
6.4.5
Maintenance
Leak test
It is recommended to perform a leak test every 3 months or when errors occur.
1) Prewet tips as described above.
2) In the Pipet/Mix mode, program the VIAFLO II Electronic Pipettes to aspirate full
volume at speed 6 and mix at full volume. Set to mix to 6 cycles and set mixing speed
at 6.
3) Aspirate full volume and verify liquid level is not decreasing during 2-3 seconds while
GripTips are still in distilled water.
4) Remove the GripTips from the liquid and hold the pipette at a 30° angle. Wait for 20
seconds.
a) Observe whether liquid droplets are forming at the end of the GripTips.
b) On a multichannel pipette, verify liquid level is even across all channels.
5) Immerse GripTips approx. 2 mm into distilled water and press Run Key to start mix
cycle.
a) Observe whether air bubbles are forming when dispensing.
b) On a multichannel pipette, check whether the levels stay approximately on the
same level across all channels.
c) At the end of a last dispense it is normal to have air bubbles because a blow-out is
performed.
Signs indicating a leak
1) During the mix cycle in the leak test, the liquid level of 1 channel is decreasing.
NOTE
A decreasing liquid level at aspiration could be an indication of a slow leak.
Performing a retest at 10 mixes may help identify a slow leak.
2) Liquid is left in a tip after the last dispense during the leak test.
3) One or more channels show air bubbles during the mix cycle in the leak test.
4) Droplets are forming when holding the pipette in the air for 20 seconds, even if a prewet was performed.
5) The liquid levels are not equal on all channels after aspiration.
If the pipette is leaking, change O-rings (see 6.3.2) and lubricate pistons (see 6.3.3) or
contact your service technician.

Maintenance
Obtaining the Actual Volume
INTEGRA certifies the pipettes at 10%, 50% and 100% of the nominal value. For each
volume 5 measurements are taken from all channels.
General
1) Always use new, unused GripTips, also when changing the test volume (e.g. from
125 µl to 12.5 µl).
2) Always pre-wet (section 6.4.4) when using a new GripTip. For a low volume
measurement, first select the maximum volume for the pre-wet and then change to the
volume to be measured.
3) After dispensing, perform a touch off to make sure no liquid remains on the tip.
Gravimetric testing
1) Write down the ambient temperature and air pressure.
2) Perform a pre-wet, see 6.4.4.
3) In the Pipet mode program the high test volume and set pipette to dispense at speed
8 for 125 µl and 300 µl and speed 6 for 12.5 µl, 1250 µl and 5000 µl.
4) The first and second dispense to the balance should not be recorded. After each
dispense re-tare the balance.
5) Aspirate the Target volume of water keeping the pipette in a vertical to 30-degree
position while immersing the pipet tip 2–3 mm below the surface of the water. When
withdrawing the tip from the liquid, gently wipe the tip against the side wall of the vessel
to remove any liquid from the outside of the pipet tip.
6) Start the first measurement. Always pipet directly into the liquid of the weigh container
on the balance. During dispense, keep the run button pressed until the pipette is
removed again from the weigh vessel to perform a 2-step blowout. Record the weight
from the balance.
7) After completing the 5 high volume measurements, continue with the mid and low test
measurements by repeating steps 2-6.

Calculation of accuracy and precision
Accuracy
The ability of a pipette to aspirate or dispense the exact volume desired. It indicates the
proximity of measurement results to the true value. Accuracy is also know as systematic
error and as the name indicates, can be corrected/calibrated.
Precision, Coefficient of variation (CV)
Precision indicates the repeatability or reproducibility of the measurement. It is also called
random error and is therefore an unpredictable error, which can not be corrected/
calibrated.
The following symbols are used throughout this text:
Actual V
Target Vs
Vs = Selected test or target Volume
mi = Measured Liquid Weight (g)
Accuracy
Z

n
= Z factor, see 7.6
= Converted Volume (ml or µl)
= Actual mean Volume (ml or µl)
= Number of measurements
Precision
Conversion of the mass to volume
The values obtained by balance readings are in grams. These values need to be
converted to micro liters using the Z correction factor. It takes into account the water
density and air buoyancy during weighing at the corresponding test temperature. To
determine the correct Z factor, find the intersection between temperature and air pressure
in Table 7.6. Round up temperature and air pressure values.
Multiply each weight mi obtained in 6.4.6 with the corresponding Z factor:
Vi = mi  Z
Add together the volumes Vi delivered, divide the sum by n (e.g. n = 5) to calculate the
mean volume V (in milliliters or micro liters) delivered at the test temperature, which is the
Actual Volume:

Calculation of systematic error (Accuracy)
The systematic error es can be calculated using the following equation with Vs being the
selected test volume:
e s = V  Vs
or in percent:
100   V  Vs 
e s = ----------------------------------Vs
Calculation of random error (Precision %)
To calculate the random error as the repeatability standard deviation sr, use the following
equation:
n

 Vi – V 

s r = -------------------------------

n–1
The random error can also be expressed as a percentage, by the coefficient of variation
CV, using equation:
sr
CV = 100  ---V
If the pipette is properly calibrated, the Target volume Vs should equal the Actual volume
V within the accuracy specifications of the pipette.
6.4.8
Adjusting VIAFLO II Electronic Pipettes
Compare the calculated accuracy and precision values with the corresponding pipette
specifications given in section 7.5.
In case a VIAFLO II Electronic pipette has not met the calibration specifications it needs
to be adjusted. This can easily be corrected by the pipette’s software.
There are two modes for calibration of VIAFLO II Pipettes, “Pipette” calibration mode, for
neat transfers and “Repeat“ calibration mode for pipetting aliquots.
The industry standard is to test and present specifications using neat transfers. This is
aspirating and dispensing the same volume. The “Pipette” factor of the pipette’s software
determines the performance of neat transfers and is therefore adjusted in case a pipette
performs out of specifications. Adjusting a pipette in “Repeat” calibration mode is normally
not required and is not described in this document.
