1 - INTRODUCTION
The Assist pipette is a volumetric instrument designed to
measure and transfer liquids precisely and safely. It can
accommodate volumes from 0.1 µl to 10,000 µl depending
on the model.
The multichannel pipettes have been designed for the filling
of laboratory microplates. The pipettes enable precise and
simultaneous delivery of 8 or 12 preset-volume doses of
liquid. The multichannel pipettes are produced in four ranges
of volumes: 0,5-10 μl, 5-50 μl, 20-200 μl, 50-300 μl.
All Assist pipettes feature a analog counter which shows the
pipetting volume. The set volume is visible in the window on
the handle. Volumes are set by either turning the pipetting
pushbutton (Fig. 1A2) or the adjustment knob (Fig. 1B) in the
appropriate direction.
Liquids are aspirated into disposable tips attached to the
pipette shaft. Disposable tips ensure maximum safety and
eliminate the possibility of crosscontamination of the liquid
samples.
To protect the user from contaminated tips, the Assist pipette
is equipped with a built-in tip ejector, (Fig. 1D).
The construction of the ejector enables the user to set up
the length. The adjustable tip ejector accommodates every
variety of tips available on the market. When using narrow
tubes, it may be necessary to remove the tip ejector. It is
simply removed by pulling down.
Single channel pipette's ejector
Adjusting of the Tip Ejector Length
- in 2-1,000 µl pipettes (Fig. 5A):
The regulated "H" spacers, allow for regulating the length of
tip ejector by +1 mm or +2 mm. An "H0" spacer is inserted
on a standard basis.
- in 5,000 and 10,000 µl pipettes (Fig. 5B):
The length of tip ejector is adjusted by screwing in or screw-
ing out the tip ejector rod with a small screwdriver. Turn the
screwdriver counter clockwise to increase the length of tip
ejector, and clockwise to reduce the length of tip ejector. The
ejector can be adjusted by up to 5 mm.
If the ejector adjustment described above is not sufficient or
the diameter of the ejector opening is too large to eject the
tip it will be necessary to put the ejector cap "M" onto the
ejector, (Fig. 5C).
