Materiali di riferimento

Il marchio VWR Chemicals include 7 diverse gamme per misurazioni fisiche: standard di colore e UV, standard di viscosità, standard per punto di fusione, standard di densità, standard per indice di rifrazione e standard COD

Una gamma completa di standard AAS, ICP e ICP-MS per l'analisi di tracce di metalli.

Tutti gli standard e i materiali di riferimento per elettrochimica vengono ora testati da un laboratorio di controllo qualità accreditato allo standard ISO EN 17025.
