Comparison of piston-operated volumetric instruments

Project Description

Three different piston-operated volumetric instruments (micropipette, glass syringe and piston burette) shall be circulated to 11 laboratories in Europe for calibration. The calibration of the volumetric instruments will consist of the determination of the amount of water the volumetric instruments deliver at a reference temperature of 20º C, using the gravimetric method.

DMDM and IPQ have provided the transfer standards.
