Pipettes are laboratory tools for collecting, transporting, and dispensing a small amount of liquid. Sometimes called pipets, pipettors, or chemical droppers, a pipette is composed of a tube that collects the measured substance and a mechanism to aspirate and dispense the substance. Some pipettes can measure a fixed volume of liquid, others are graduated to show the volume, while others can be set to measure a volume within a range. Pipettes can aspirate and dispense liquid manually, electronically, or with a pipette filler that can be motorized. Pipettes are available in a variety of sizes and designs, offer ergonomic features for often-repeated functions, can be autoclavable for reuse, or disposable. The type of pipette used is determined by laboratory applications. Pipettes are typically used in medicine, biology, chemistry, and biotechnology for liquid handling, sampling, testing, and cell culture applications.
