Micropipette ( Mline)

Micropipettes are commonly used in molecular biology as well as medical tests. Micropipettes come in several designs for various purposes with differing levels of accuracy and precision, from single-piece glass pipettes to more complex adjustable or electronic pipettes. Many micropipette types work by creating a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense.

Micropipettes that dispense between 1 and 10000UL are termed Micropipette, while micropipettes dispense a greater volume of liquid. Two types of micropipettes are generally used: air-displacement pipettes and positive-displacement pipettes. In particular, piston-driven air-displacement pipettes are micropipettes that dispense an adjustable volume of liquid from a disposable tip. The pipette body contains a plunger, which provides the suction to pull liquid into the tip when the piston is compressed and released.

The maximum displacement of the plunger is set by a dial on the micropipette body, allowing the delivery volume to be changed. Larger capacity tubular pipettes, such as volumetric or graduated pipettes are used by temporarily attaching a pipetting aid. Micropipettes typically handle volumes in the 0.5ul to 10,000ul range, for aliquot transfer and incremental dispensing in titrations, with a positive displacement method of operation
