If the average aspirated volume exceeds the permissible
value, the following should be done:
• Remove the pipetting pushbutton, (Fig. 4A)
Warning: The pipetting pushbutton consists of 2
parts: the knob (Fig. 1A2) and the pushbutton
(Fig. 1A1). After removal of pushbutton, both parts
are separated.
• Holding the volume adjustment knob to protect it
against rotation, insert the calibration key into the cuts
of the calibration screw, (Fig. 4B)
• Turn the key clockwise to reduce the aspirated volume,
or counter-clockwise to increase the volume,
(Fig. 4C). One full turn of the calibration key changes
the pipettor aspiration volume by the amount given in
the table
• Take out the key and fix the pipetting push-button,
(Fig. 4D). The pipetting pushbutton should be fixed in
opposite order.
Determine the average aspirated volume. The average
volume should be within the permissible range given in
the table. If the volume exceeds the values stated, the
recalibration procedure should be repeated.

6 - CLEANING AND STERILIZATION

Cleaning:
External surfaces of the pipetting pushbutton, the ejector
pushbutton, the handgrip, the shafts and the adjust-
ment knob may be cleaned using a cloth dampened in
isopropyl alcohol.
Sterilization:
The pipettors can be sterilized in the autoclave at 121°C
for 20 minutes maximum. Exceeding the recommended
autoclaving temperature or time will cause damage to
the pipettor and will void the waranty. After sterilization,
the pipettor should be dried and cooled down to room
temperature.
It is recommended:
- to sterilize the pipettors in autoclave with an initial va-
cuum and drying cycle.
- prior to sterilization to unscrew the nut connecting the
handle and module slightly. After autoclaving these
parts should be screwed tight again.
- to set the locking ring in lower (unlocked) position
prior to sterilization.
- to test pipettor calibration every 10 sterilization cycles.
