Micropipettes are used to accurately measure and dispense small volumes of liquid. The capacity of a micropipette can range from less than 1μl to 1000μl (1ml). To ensure that obtained results using micropipette are reliable, it is necessary to calibrate micropipettes several times a year. This video shows a method for testing the accuracy of automatic micropipettes.
Pipetman is a precision instrument and should be treated with the level of care appropriate for laboratory instrumentation. This video provides some pipetting guidelines and precautions.
