Pipette Tip Bend Test

A pipette (also spelled pipet or pipettor) is used to aspirate and dispense fluids in wells for analysis and further testing.  There are many types of piston pipettes, but all work on essentially the same principle; hand or mechanical pressure on a piston or plunger working over a fixed length in a cylinder forces a pre-determined volume of liquid out of the orifice of the pipette.  Pipettes are used to hold body fluids, oily fluids, concentrated acids, nucleic acids, and volatile compounds.
