Positive Displacement Pipettes For Precise Measurement

Positive Displacement Pipettes are precision instruments designed to handle small volumes of liquids, including viscous, volatile, or dense samples that are difficult to measure with air-displacement pipettes. They operate by directly moving a piston within a disposable tip or capillary, ensuring accurate and repeatable delivery without air cushion interference. Widely used in molecular biology, clinical diagnostics, and pharmaceutical laboratories, positive displacement pipettes are ideal for handling samples such as blood, oils, or glycerol solutions where standard pipettes may be less reliable.
