Normax Volumetric Flask Amber Glass with Glass Stopper 31 886 07V (5 mL)
The Normax Volumetric Flask 31 886 07V (5 mL) is designed for laboratories that require high-precision Class A measurements while protecting light-sensitive solutions. Its amber borosilicate glass reduces UV and visible light exposure, helping maintain sample stability. The ground glass stopper creates a secure seal, and the white graduation mark provides sharp visibility for accurate meniscus alignment. Normax manufactures this flask in compliance with ISO 1042 and supplies a Certificate of Performance, ensuring verified and traceable calibration.
