Pipette Overview
[Purge]
The Purge key enters a purge prompt anytime during a pipetting
operation to abort the program. By pressing the Purge key, then
pressing the trigger, you can dispense any remaining liquid from
the pipette tips and return to the beginning of the program.
The Purge key is also used to enter the purge step into a
program.
Note:
If there is insufficient liquid for a final dispense step, the
pipette emits a beep tone and automatically displays the purge
prompt.
Note:
The RUN mode performs the operation that is displayed, such as fill, dispense,
mix, or purge. When “Run” appears in the display, you can activate the RUN mode by
pressing the trigger. At the end of a pipetting sequence, the pipette emits a triple beep
tone and returns to the beginning of the program. The pipette remains in RUN mode
until you program a new pipetting sequence.
B.3.2 Programming Keys
[Fill]
[Disp]
[Mix]
The Fill, Dispense, and Mix keys program the pipetting operations.
By pressing the fill or mix key, you can enter the programming
mode of the electronic pipette. The “Run” prompt disappears from
the display and the appropriate operation appears with a flashing
“Vol” prompt. Fill, dispense, or mix volumes can be programmed
by pressing the Volume key. Also, the number of mix cycles can
be programmed by pressing the Mix key twice.
Automatic blowout:
At the end of a final dispense step, the
pipette automatically expels any remaining liquid from the pipette
tips with a short burst of air (
blowout
). The pistons then reverse
direction and return to zero position.
