Normax Volumetric Flask Amber Glass Glass Stopper 200mL

Normax Volumetric Flask Amber Glass with Glass Stopper 31 886 32V (200 mL)

The Normax Volumetric Flask 31 886 32V (200 mL) combines Class A measurement accuracy with maximum protection for light-sensitive solutions. Its amber borosilicate glass reduces UV and visible light exposure, helping preserve the stability of photoreactive chemicals. The ground glass stopper provides a reliable, airtight seal, while the white graduation mark offers high contrast against the amber body for precise meniscus reading. Manufactured according to ISO 1042, each unit includes a Certificate of Performance, ensuring verified and traceable calibration.
