Normax Volumetric Flask Amber Glass Plastic Stopper 5mL

Normax Volumetric Flask Amber Glass with Plastic Stopper 31 886 06 (5 mL)

The Normax Volumetric Flask 31 886 06 (5 mL) combines Class A volumetric accuracy with maximum protection for light-sensitive solutions. Constructed from amber borosilicate glass, the flask minimizes UV and visible light exposure, helping maintain the stability of photoreactive chemicals. The plastic stopper provides a lightweight and secure seal, while the white graduation mark gives a bright, high-contrast reference for precise meniscus alignment. Manufactured according to ISO 1042, each flask includes a Certificate of Performance, ensuring traceable and verified calibration for analytical and regulated workflows.
