Normax Volumetric Flask Amber Glass with Glass Stopper 31 886 17V (50 mL)
The Normax Volumetric Flask 31 886 17V (50 mL) offers Class A measurement accuracy while protecting light-sensitive solutions. Its amber borosilicate glass reduces UV and visible light exposure, helping maintain chemical stability during preparation and storage. The ground glass stopper provides a secure, airtight seal, and the white graduation line delivers a clear, high-contrast reading for precise meniscus alignment. Manufactured according to ISO 1042, each flask includes a Certificate of Performance, ensuring traceable and verified calibration.
