50ml Borosilicate Glass Volumetric Flask with Plastic Stopper – Class A
The Glassco 50 mL Class A volumetric flask gives you traceable accuracy for preparing and measuring laboratory solutions with confidence. Manufactured from ASTM E438 Type I Class A Borosilicate Glass 3.3, it provides chemical resistance, dimensional precision and long-term stability under analytical conditions.
Each flask is calibrated to ISO 1042 and marked with a blue printed graduation and a finely diamond ground meniscus for precise visual reference. The precision formed neck supports smooth filling to the calibration line, whilst the plastic stopper ensures a tight, inert seal that prevents contamination or evaporation. Batch certification confirms traceable volumetric accuracy, supporting consistent calibration in regulated environments. Designed for busy analytical labs, it maintains measurement integrity through frequent use.
