Fitting the tips
VWR High Performance Pipettor have been designed to
fit VWR tips.
Pre-rinse the tips
Some liquids (e.g.protein-containing solutions and
organic solvents) can leave a film of liquid on the inside
wall of the tip; pre-rinse the tip to minimize any errors
that may be related to this phenomenon.
Pre-rinsing consists of aspirating the first volume of
liquid and then dispensing it to waste. Tips will not fall
off nor will they have to be manually positioned.
Make sure first that the pipette is calibrated with the
tips that you are using. Then, subsequent volumes that
you pipette will have levels of accuracy and precision
within specifications. Using other tips may require a
validation of the pipetting system.
