Normax Volumetric Flask Amber Glass with Plastic Stopper 31 886 26 (100 mL)
The Normax Volumetric Flask 31 886 26 (100 mL) delivers Class A precision with enhanced protection for light-sensitive chemicals. Constructed from amber borosilicate glass, the flask blocks UV and visible light, helping maintain the stability of photoreactive reagents. The plastic stopper provides a secure, lightweight seal, while the white graduation mark ensures high-contrast visibility for precise meniscus reading. Manufactured according to ISO 1042, each flask includes a Certificate of Performance, confirming traceable and verified calibration.
