Peri-pump Dispenser Maintenance

The level of the maintenance required to keep the dispenser/washer performing as
expected is highly dependent on several factors, including the type of fluid
dispensed, the frequency of dispensing, and the work habits employed. For
example, when dispensing fluids that can crystallize or harden after use,
maintenance activities are required more frequently.

When using the 1 µL cassette filter fluids to 50 microns to reduce the chance of tips

clogging. 

Daily maintenance includes purging the fluid at the end of a dispense run and
flushing the tubing with water (or buffered saline and then water). This is a good
practice whenever the dispenser will be idle for more than an hour, as well as at
the end of the day.

Another important daily requirement is keeping track of the number of plates
processed with a cassette. This is necessary to determine when the cassette has
reached its expected lifetime and is due for replacement or recalibration.
Replacement Tubing Kits, a refurbishment service, and new cassettes are available
from BioTek Instruments.

Monthly maintenance requires overall cleaning of the dispenser and its accessories,
and verifying performance to determine if the cassette needs recalibration.
Autoclaving or decontaminating the cassette is also recommended.

Peri-pump Maintenance Tasks:

l

Flush the Dispense Cassette below

l

Unclog the Dispense Tips on page 194

l

Record the Number of Plates Processed on page 199

l

RAD 8-to-1 Cassette - Replace Chute on page 200

l

Recalibrate the Peri-pump Dispense Cassette on page 211

l

Replace Peri-pump Dispense Cassette Tubing on page 210

Flush the Dispense Cassette

Prime the tubing with an appropriate reagent at the beginning of the day, and,
flush the tubing to effectively remove all contaminants at the end of the day.
