2.8 Marking the Xplorer pipette to show the adjustment has been changed
You must carry out a gravimetric test of each Xplorer pipette whose factory setting you have changed by
selecting and carrying out one of the previously described adjustments. This is the only way of ensuring
that the selected adjustment meets your requirements regarding precision and accuracy.
1. Mark each Xplorer pipette whose adjustment has been changed with a clearly visible label indicating
the type of change made.
2. Indicate all the key information on the liquid and steps carried out on the label.
3. If the temperature of the liquid is different to that of the Xplorer pipette and the pipette tips, record the
number of piston strokes required for prewetting the pipette tips on the pipette label.
In the lab journal, record the weighing results and all the general conditions for which you have
changed the adjustment. In the lab journal, note the conditions in which the readjusted Xplorer pipette
has to be operated:
•
How the blow-out (blow) is performed
• Volume range
• Operating mode
• Pipette tip type (for example, filter, LoRetention, long)
• Frequency of tip replacement
• Frequency of prewetting the tip
• Special angle of inclination during aspiration and dispensing
• Special work technique (for example, "reverse pipetting")
• Liquid (name, composition, density)
• Aspiration speed (speed)
• Dispensing speed (speed)
• Temperature
This way you can ensure that other users will be informed of the changes to the adjustment, in addition to
the information provided in the header of the display. This allows the Xplorer pipette to be operated exactly
according to the general conditions for the changed adjustment.
You can repeatedly change an existing 1 - 3 point adjustment. Each change is proceeded by a confirmation
request. After a 1 – 3 point adjustment has been changed, the corresponding symbol appears unchanged in
the header.
