C.4 Programming Examples
Examples of different pipetting sequences are described below.
These examples are ideal for use as training exercises. Press the
keys shown in keycaps [ ], then press the [Vol] key until the
volume in parentheses ( ) is displayed. At the end of the program,
a triple beep tone is sounded. See Section F, Appendices, for
additional pipetting examples.
C.4.1 Sample Transfers
Example: Fill and dispense 100 µl.
Option 1 Option 2
[Fill]
s
t
Vol
(100) [Enter]
OR
[Fill]
s
t
Vol
(100)
[Enter] [Enter]
[Disp]
s
t
Vol
(100) [Enter] [Enter]
The second option is a one-step program. Because the program
ends at a volume greater than zero, and the last step is not a mix,
a "Purge" prompt automatically appears at the end of the fill to
dispense the liquid and return to the beginning of the program.
C.4.2 Incremental Pipetting
Example: Fill 250 µl and dispense 45 µl in 5 increments.
[Fill]
s
t
Vol
(250) [Enter]
[Disp]
s

Vol
(45) [Enter] [Enter]
In this program, only one dispense step needs to be programmed.
If any program ends in a dispense step, the pipettor repeats the
dispense step until the volume is zero, or is less than the
programmed dispense volume. If the remaining volume is less than
the programmed dispense volume, the pipettor displays a "Purge"
prompt to discard the remainder.
