Normax Volumetric Flask Amber Glass Glass Stopper 20mL
The Normax Volumetric Flask 31 886 12V (20 mL) offers Class A volumetric accuracy while protecting light-sensitive chemicals. Made from amber borosilicate glass, this flask shields reagents from UV and visible light, helping maintain chemical stability during preparation and storage. Its ground glass stopper seals the flask securely, and the white graduation mark provides a bright, high-contrast reference for accurate meniscus reading. Produced under ISO 1042, each flask is supplied with a Certificate of Performance, ensuring verified and traceable calibration.
