PIP – precise pipetting/diluting
Example: Pipet 1mL and dilute with 9mL. Distilled water is used as the
"hydraulic“ liquid.
Preconditions / Preparation
The easiest and most accurate means of pipetting is with pipetting attach-
ment 6.1562.040. The keyboard can be used to proceed from step to step.
Define a dosing unit which corresponds to the tubing of the Dosino used.
This procedure is described on page 22. (This is not necessary if the pipet-
ting attachment is used as this corresponds to the standard settings.)
