The micropipette is used to transfer small amounts (< 1 ml) of liquids. The scales on
micropipettes are in microliters (1000 !l = 1 ml). The brand of micropipettes we will be using is
made by Rainin and called a “Pipetman”. These are very expensive, delicate instruments costing
$250-300 apiece. We have four sizes identified by the number on the round button on the
plunger. The value is the maximum volume in microliters that can be transferred with that size
pipette. They are used in conjunction with disposable sterile plastic tips.
