Normax Volumetric Flask Amber Glass Plastic Stopper 200mL

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

The Normax Volumetric Flask 31 886 32 (200 mL) combines Class A measurement accuracy with strong protection for light-sensitive reagents. Manufactured from amber borosilicate glass, the flask reduces UV and visible light exposure, helping preserve the stability of photoreactive chemicals. The plastic stopper provides a lightweight, secure seal, while the white graduation mark offers sharp contrast for precise and consistent meniscus reading. Produced in accordance with ISO 1042, each flask is supplied with a Certificate of Performance, ensuring verified and traceable calibration.
