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.
