Normax Volumetric Flask Amber Glass Glass Stopper 500mL

Normax Volumetric Flask Amber Glass with Glass Stopper 31 886 44V (500 mL)

The Normax Volumetric Flask 31 886 44V (500 mL) offers Class A volumetric precision while ensuring reliable protection for light-sensitive reagents. Made from amber borosilicate glass, the flask minimizes exposure to UV and visible light, preserving the chemical stability of sensitive solutions. The ground glass stopper provides a secure, airtight seal, while the white graduation mark gives a sharp, high-contrast reference point for accurate meniscus alignment. Manufactured in compliance with ISO 1042, each flask includes a Certificate of Performance, ensuring verified and traceable calibration.
