Normax Volumetric Flask Amber Glass Plastic Stopper 10mL

Normax Volumetric Flask Amber Glass with Plastic Stopper 31 886 09 (10 mL)

The Normax Volumetric Flask 31 886 09 (10 mL) combines Class A measurement accuracy with excellent protection for light-sensitive reagents. Made from amber borosilicate glass, it blocks UV and visible light, helping preserve the stability of photoreactive chemicals. The plastic stopper creates a secure and lightweight seal, while the white graduation mark provides a bright, high-contrast reference for precise meniscus alignment. Produced according to ISO 1042, the flask includes a Certificate of Performance, ensuring traceable and validated calibration.
