Liquid type ethanol 75%

The factory setting is changed by a factor in order to allow 75% ethanol to be dispensed with higher
accuracy (smaller systematic error) with the Xplorer pipette. The internally used factor takes into account
the density. Perform pipetting with this adjustment in the

Pip operating mode as follows:

1. Hold the Xplorer pipette vertically and prewet the tip with liquid three times at room temperature. Make

sure that no outer wetting remains on the tip.

2. Use speed level 5 (standard setting) for aspiration and dispensing.

3. Dispense liquid at a slight angle against the wall of the tube of the destination tube.

4. About 2 seconds after dispensing keep the rocker pressed to trigger the blow-out (blow). Only release

the rocker after leaving the dispensing vessel.

5. Eject the pipette tip.

2.4

Liquid type glycerol 50%

The factory setting is changed by a factor in order to allow 50

% glycerol to be dispensed with higher

accuracy (smaller systematic error). The internally used factor takes into account the density of the 50%
glycerol and the same work technique as described for ethanol

75% in the

Pip mode.
