Calibration of pipettes by gravimetry

The recommended calibration method is the gravimetric method according toISO 8655-6, with 10 weighings.However, any other method may be used.

Pipettes caracteristics

  • 1 automatic pipette with variable volume 5-50μl,
  • 1 automatic pipette with variable volume 10-100μl,
  • 1 automatic pipette with variable volume 100-1000µl.

Organization of the PT

Each laboratory will have to calibrate the pipettes within a week. The instruments will circulate from one laboratory to another from September 2021.
