Brinkmann/Eppendorf SOP,,, Standard Operating Procedure for Pipettes

Bottletop Dispenser: Adjust the ChemSaver Bottletop Dispenser by turning the fine adjustment (see Fig. 8). One rotation is equivalent to the smallest dispensing step.
Rotation of the button in the + direction: increase in volume.
Rotation of the button in the direction: decrease in volume.
(Factory-set adjustment at 20 C with degassed, bidistilled water; see instruction manual.)
8.3 Adjusting for liquids with a density different to that of bidistilled, degassed water It is possible to adjust the pipettes described on the previous pages for one volume of a liquid with a density different to that of water so that the volume displayed corresponds with the pipetted volume.

Caution: With adjustable pipettes, all other values are then adjusted as well!

The adjustment process is similar to the procedure described in Sec. 8.1 and 8.2. The difference is the mean value of the weighings is converted into microliters using the following formula:

Mean value of weighings Pipetting volume=
Density of liquid weighed
The resulting value is the actual value to which the volume display of adjustable-volume
