Supplier: VWR Chemicals

These standards are for the calibration of refractometers prior to use.

Supplier: Merck

In de Europese Farmacopee worden diverse referentiematerialen beschreven voor de controle van refractometers (bijv. Ph Eur. 2.2.6). In dit geval worden de stoffen trimethylpentaan, tolueen en methylnaftaleen voorgeschreven. Deze instrumententest moet voor elke analyse worden uitgevoerd. De uitgebreide productreeks omvat standaarden die geschikt zijn voor nagenoeg elk werkbereik; het bereik 1.3915-1.6160 (20 °C) is hier van toepassing.
