Add to My manuals

The RT-2600C Microplate Washer is a microprocessor controlled Microplate washing system that performs wash protocols defined by the user. It is designed to wash all of the wells in one column or row of a 96-well plate at once. The washing protocol can be programmed so that either all of the columns (or rows) are washed in the same manner or different wash cycles can be applied to specific columns (or rows) on the plate.

Users can adjust the position of the dispensing head within the range of ± 1mm in both, vertical and horizontal direction, so as to adapt the to microplates of different specifications.

In the horizontal direction the liquid suction needle (the thick, long needle) is required to be put at the center of the Microplate well.

In vertical direction, the liquid suction needle is required to fall completely onto the bottom of the Microplate well. A clearance of 0.5 to 1mm is recommended between the steel pin of the dispensing head and the fillister of the supporting arm groove.

5. MAINTENANCE AND CLEANING

5.1. Daily maintenance of worktable

There is often remnant liquid on the worktable, and excessive liquid may spill over the edge of the worktable and seep into the instrument. Therefore, it is necessary to wipe off remnant liquid on the worktable from time to time. Use tweezers to nip a small piece of absorbent cotton to wipe the worktable. Use caution that the head of the tweezers don’t scratch the surface of the worktable.

5.2. Maintenance of dispensing head

The dispensing head is one of the core components of the RT-2600C, whose condition has an influence on the accuracy of the amount of dispensation as well as the amount of remnant liquid. Therefore, the maintenance of the dispensing head is of high significance. The maintenance procedure is as follows: z Switch off the electric source of the machine. z Remove the tubes by twisting counterclockwise. z Put the dispensing head from the supporting arm. z Remove the two metal screws on the front side of the dispensing head. z Use the small-sized needle to clear out each dispensing needle (short, thin needle) and use the large-sized needle to clear out each liquor suction needle (long, thick needle). z Take the dispensing head with the screw-removed end downward. Knock it against a paper towel or gauze so as to remove the blocking from the tubing. z Put the O-ring around the root of the metal screws and tighten the two screws up

Note

!

the O-rings must be put around the screws so as to guarantee hermeticity.

z Fill up a large container with distilled water and immerse the dispensing head completely in the water. Plug a large-size syringe into the plastic hole on the dispensing head and push the syringe back and forth for several times. Both plastic holes will be treated this way. z Mount the dispending head back onto the supporting arm and tighten up the plastic tubes clockwise

Note

!

assure that the tubes are connected according to their color code.

23

RT-2600C User’s Manual

5.3. Waste bottle treatment

The sensors in the waste bottle can sense the liquid height. If the waste liquid reaches a certain height, the software of the RT-2600C detects the change of the sensor signal and stops any operation that involves liquid suction.

At this time, please dispose the waste liquid timely, which can be done without disconnecting the electrical source. z Hold the top of the waste bottle with one hand and lift it slightly. z Hold the body of the waste bottle with the other hand and turn clockwise until the top is detached from the bottle body. z Pour away the waste liquid. z Put the tube endings and the sensor back into the waste bottle and close it by turning the bottle counterclockwise.

5.4. Maintenance of the wash bottle

Fill up the wash bottle with distilled water to wash the blank plate once a week and clean up the whole pore path and the diving pump.

Note

!

The water level in the wash bottle should be higher than the diving pump inside to avoid the aspiration of air.
