Insert pipette (glass/plastic) inside
the collet. The collet’s internal
knurling will hold it firmly in place.
Press the upward plunger
(look for the ‘up’ mark) to aspirate
liquid into the pipette and downward
plunger (look for the ‘down’ mark)
to dispense liquid. (Fig.3.1)
Before autoclaving, disassemble
the collet assembly by unscrewing
it and then proceed. (Fig 3.3)
Please note that only the collet
assembly is autoclavable and
NOT the entire instrument.
A thumb wheel at the back of the instrument
facilitates convenient pump speed adjustments
during liquid handling.
Rotate the wheel clockwise to increase the pump
speed and anticlockwise to reduce it. (Fig 3.2)
