6.9 Shutdown
Chapter 6: Routine Operation
Remove any microplates still on the plate carrier. Dispose of all microplates and strips as
biohazardous waste.
After all the plates have been dispensed, press the empty key to return the reagent or liquid from the
tubes to the reservoir. This saves expensive reagents.
If there is only a short break in dispensing, no washing or cleaning of the tubes is necessary.
However, after pressing the empty key, release the tubing tension by pulling the upper part of the
cassette from its slots and place it into its rest position slots located on the left-hand side of the rotor
(Fig. 6.18).
If there is a longer break (for example, a day), wash the dispensing cassette by priming it with
deionized distilled water or with special washing detergent if necessary.
After washing, store the dispensing cassette in the rest position (Fig. 6.18).
Switch the Multidrop 384 off by pressing the mains switch (Fig. 4.2) at the end of the left side panel of
the instrument into the OFF position.
Wipe the instrument surfaces with a soft cloth or tissue paper moistened with deionized distilled water,
a mild detergent (SDS, sodium dodecyl sulfate) or soap solution.
If you have spilt infectious agents on the dispenser, disinfect with 70% alcohol or some other
disinfectant (see section 7.8 Decontamination procedure).
6.10 Guidelines for use
• When the error LED is on, the start or step keys will not function.
• To clear the error and continue the dispensing procedure, press the stop key and wait until the
plate carrier has returned to the home position. The dispensing procedure can then be restarted.
• If you press the stop key, all operations will stop. The plate carrier is automatically returned to
the home position. The Multidrop 384 will now require priming again.
• Preventative maintenance should be followed closely to keep the microplate dispenser in the best
condition for maximum reliability. A poorly maintained instrument will not give the best results.
