Micropipette (Piston-Operated Pipette)

A hand-held, piston-operated device that measures and dispenses small liquid volumes, typically 0.1 µL to 10 mL, using disposable tips. Used for standards, dilutions, microbiology and bioassays.

CALIBRATION

Micropipette calibration procedures

Gravimetric accuracy & precision

Weighs repeated deliveries of water from the pipette, converts mass to volume with a Z factor, and calculates systematic and random error as in ISO 8655-6.

QUALIFICATION

Instrument qualification (DQ · IQ · OQ · PQ)

  1. 01

    DQ — Design qualification

    Defines volume range, type (air or positive displacement), number of channels and tip compatibility.

  2. 02

    IQ — Installation qualification

    Records identity, serial number, calibration certificate and asset number.

  3. 03

    OQ — Operational qualification

    Gravimetric check of accuracy and precision at several volumes per ISO 8655-6.

  4. 04

    PQ — Performance qualification

    Periodic gravimetric checks and in-use performance; many labs combine OQ and PQ as routine calibration.
