That’s What We Do at RADWAG Measurement Laboratory: Calibration of Piston Pipettes

In previous articles, we described the procedures for calibration of non-automatic electronic balances and mass standards carried out at the accredited RADWAG Measurement Laboratory. Today, we will explain what the calibration of piston pipettes is all about; you can outsource this procedure to our Laboratory.

 

Piston pipette – what is it?

A piston pipette, or automatic pipette, is a measuring instrument designed for measuring and transferring liquids. By design, we distinguish between single-channel and multi-channel pipettes, and by volume – fixed and variable volume pipettes.

 

What is the calibration of piston pipettes?

The calibration procedure for piston pipettes includes:

  • determination of systematic and random error,
  • indication of the pipette for the volume under test, together with the measurement uncertainty.

RADWAG Measurement Laboratory calibrates piston pipettes in accordance with ISO 8655 standard.
