Normax Volumetric Flask Amber Glass Glass Stopper 10mL

Normax Volumetric Flask Amber Glass with Glass Stopper 31 886 08V (10 mL)

The Normax Volumetric Flask 31 886 08V (10 mL) ensures Class A accuracy while offering full protection for light-sensitive solutions. Manufactured from amber borosilicate glass, the flask blocks UV and visible light to maintain reagent stability. The ground glass stopper provides a secure seal, and the white graduation line gives a sharp, high-contrast reference for precise meniscus reading. Produced in accordance with ISO 1042, each flask comes with a Certificate of Performance, guaranteeing verified and traceable calibration.
