Wash Fluid
A single wash fluid is used on the Opsys MW™ Microplate Washer. The
wash fluid is contained in the Wash Container and is dispensed into the
wells whenever a Dispense or Fill operation is specified in the wash
protocol. In addition, wash fluid is dispensed into the purge tray during a
Purge operation.
Dispensing of the fluid from the Wash Container is controlled by a pump
attached to the back of the Opsys MW™ Microplate Washer and a dispense
valve located near the wash head (Figure 1).
Waste
Fluid is removed from the wells during an Aspirate or Dispense operation
and collected in the Waste Container. The Waste Container contains a level
sensor to alert the operator when the container is full.
Removal of the fluid from wells is controlled by lowering the wash head so
that the aspiration pins are immersed into the well fluid (the aspiration
height). A vacuum is applied to the aspiration pins at all times during
operation so that the contents of a well are aspirated whenever the wash
head is lowered to the aspiration height.
