Measuring and dispensing small volumes of a variety of liquids is a critical part of many biology and chemistry laboratory procedures. The smaller the volumes, the more difficult this is, and the more important it is to do so accurately and precisely. Micropipettes are sophisticated instruments designed specifically to measure and dispense small volumes. This video, adapted from the University of Leicester, describes the basic function of a variety of micropipettes. It also demonstrates their proper use and the errors that can result if proper techniques and procedures aren’t followed.
