Pipettes / Pipettors

Pipettes are an essential laboratory tool used to dispense measured volumes of liquids. Pipettes most commonly work by creating a partial vacuum above the chamber that holds the liquid and selectively releasing this vacuum to draw up and dispense according to the preferred volume. Pipettes that dispense between 1 and 1000µl are termed micropipettes, while macropipettes dispense a greater volume. Pipettes enable sterile and accurate liquid handling and are commonly used within molecular biology, analytical chemistry and medical tests. Pipettes come in several designs including manual and electronic, as well as single-channel or multi-channel pipettes, all designed for efficiency when working with varying plates, tubes, and dishes. Manufacturers continue to offer new and more efficient pipettes for a diverse number of experimental and cell culture purposes.
