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.
