If there is doubt that dispensing data are correct
To avoid dispensing errors, the precision and accuracy of the Research pro need to be checked
regularly. The PICASO II software program (see ordering information) is available to determine
permitted systematic and random measuring deviation (see Section 2 "Technical data"). An
SOP (
S tandard O perating P rocedure) for checking pipettes can be called up from our home
page www.eppendorf.com .
For liquids whose physical data deviate significantly from those of water, calibration needs to be
changed in accordance with Section 5.11.1. Calibration will also need to be changed if the
pipette is being used at a very high altitude.
