9. Enter the desired value using the keypad and press ENTER. The
display will read:
Sweep? NO
YES NO
10. Select YES to specify a sweep. The display will read:
All cycles? NO
YES NO
Note: If a sweep is specified, the wash pins
are moved up and down and across the
bottom of the well during aspiration to better
remove all droplets of liquid. If NO is selected,
the Wash height? prompt (Step 14) will be
displayed.
Note: Use the sweep function with Flat or “C”
bottom plates only. Sweeping aspirates fluid
more completely from the wells than a regular
aspiration. Sweep all cycles to get the most
thorough well aspiration when using multiple
aspiration cycles, but remember that each
sweep adds seconds to the protocol.
