5ml Borosilicate Glass Volumetric Flask With Plastic Stopper – Class A
The 5ml Borosilicate Glass Volumetric Flask With Plastic Stopper helps you achieve precise micro-volume preparation and measurement in analytical work. Manufactured from ASTM E438 Type I Class A Borosilicate Glass 3.3, it delivers consistent dimensional accuracy and resistance to chemical exposure.
Calibrated to ISO 1042, this Class A flask features a blue printed graduation and a diamond ground meniscus mark for visual clarity at a distance. The precision neck allows controlled filling to the calibration line, whilst the plastic stopper ensures a tight, inert closure. Each flask is batch certified to confirm traceable volumetric accuracy and support compliance in regulated laboratory environments. Built for busy analytical labs, it maintains calibration accuracy during continuous operation.
