4.1 Volume setting (not valid for fixed-volume model)
The volume can be changed continuously by rotating the setting ring
(Fig. 2-2). The figures in the digital display are read from top to bottom.
It is advisable to carry out volume setting from the higher down to the lower
value. i.e. first go above the desired volume and then return to the lower value.
4.2 Pipette tips
The pipette can function only when a pipette tip is attached into which the
liquid is aspirated.
To facilitate the search for a suitable tip, the color of the control buttons
corresponds to the color of the Eppendorf tip racks.
When pipetting liquids with wetting properties different to those of water, please
observe the recommendations contained in Section 4.5.
4.3 Aspirating liquid
– The liquid which is to be aspirated is taken from a suitable vessel (for multi-
channel pipettes, we recommend the reagent reservoir "Tip-Tub").
– Attach suitable tips the pipette firmly (observe the color coding).
– 1 – 10 mL model: use pipette only with filter inserted.
– Press down the control button (Fig. 2-1) to the first stop (measuring stroke).
– Immerse the pipette tip(s) approx. 3 mm into the liquid.
For Research, adjustable-volume (variable), 500–5000 µL and 1 – 10 mL:
approx. 5 mm.
– Allow the control button to slide back
slowly .
– Before removing Research, adjustable-volume (variable), 500–5000 µL and
1 – 10 mL from the liquid, wait approximately three seconds.
– Pull the tip(s) out of the liquid
slowly .
– To remove any remaining droplets, dab with non-fibrous cellulose. When doing
so, ensure that no liquid comes out of the tip(s).
