We expect pipettes to accurately dispense liquid but after a while, pipettes will need calibration. The type of calibration your pipettes need may vary depending on usage, quality systems, and more. There are two primary types of ISO pipette calibration, which are known as ISO 8655 and ISO 17025. ISO 8655:2022 defines two reference measurement procedures for pipette calibration: the gravimetric procedure (Part 6) and the photometric procedure (Part 8). Adhering to strict environmental conditions is crucial when using these reference procedures.The ISO 8655-6:2022 is an international standard for calibration and testing procedures of piston-operated volumetric apparatus like pipettes, burettes, dilutors, and dispensers, which must be performed at least once a year.
