100ml Borosilicate Glass Volumetric Flask with Plastic Stopper – Class A
The Glassco 100 mL Class A volumetric flask delivers you consistent analytical accuracy for preparation and dilution of laboratory solutions. Produced from ASTM E438 Type I Class A Borosilicate Glass 3.3, it offers chemical resistance, dimensional reliability and heat stability for consistent analytical work.
Each flask is calibrated to ISO 1042 and carries a blue printed graduation with a finely diamond ground meniscus for sharp visual alignment. The precision formed neck supports you with controlled filling to the calibration line, and the plastic stopper provides a tight, inert seal to preserve solution integrity. Each batch is certified to confirm calibration traceability and compliance with Class A volumetric standards. Built for demanding laboratories, it sustains measurement precision through regular analytical cycles.
