ENGLISH
Various volume settings for
Pipetman 8X200 are shown
opposite:
The volume is set by turning either the adjustment
screw (
Fig. 1F
) or the adjustment knob (
Fig. 2A

).
When wearing gloves, you may find it easier to use
the adjustment knob to set the volume. To obtain
maximum accuracy when changing the volumeter
setting, follow these recommendations:
• When decreasing the volume setting, turn the
adjustment ring slowly to reach the required
setting, making sure you don’t overshoot the
mark.
• When increasing the volume setting, turn the
adjustment ring until you are 1/3 of a turn
above the required setting. Then turn the
adjustment ring slowly to decrease the vol-
ume setting to the required value, making
sure you don’t overshoot the mark.
3. OPERATION
Mount new disposable tips on all eight pipette
nozzles (
Fig. 1I
) by pressing down on the
Gilson Tipack
™
rack. Use a back-and-forth or
side-to-side rocking motion to ensure that the
tips are securely mounted. Press firmly to
ensure a positive airtight seal. Set the desired
volume using the adjusting screw.
ASPIRATION
1) Press the push-button (
Fig. 2A
) to the first stop
(
Fig. 1A
). This part of the stroke is the calibrated
volume displayed on the digital volume scale.
2) Holding the 8X200 vertically, immerse the
tips into the samples to an immersion depth
of 2-4 mm.
3) Allow the push-button to return slowly and
smoothly to the top position to aspirate the
sample (
Fig. 1B
).
