Normax Volumetric Flask Amber Glass with Glass Stopper 31 886 54V (1000 mL)
The Normax Volumetric Flask 31 886 54V (1000 mL) delivers Class A volumetric accuracy combined with maximum protection for light-sensitive solutions. Its amber borosilicate glass blocks UV and visible light, maintaining the stability of photoreactive chemicals during preparation and storage. The ground glass stopper ensures a secure, airtight seal, while the white graduation line offers excellent visibility for precise and consistent meniscus alignment. Produced according to ISO 1042, each flask includes a Certificate of Performance, ensuring verified and traceable calibration.
