1000ml Borosilicate Glass Volumetric Flask With Plastic Stopper

1000ml Borosilicate Glass Volumetric Flask With Plastic Stopper

The Glassco 1000ml Borosilicate Glass Volumetric Flask With Plastic Stopper gives you traceable accuracy for precise preparation and dilution of large laboratory solution volumes. Manufactured from ASTM E438 Type I Class A Borosilicate Glass 3.3, it offers superior chemical resistance, dimensional reliability and heat stability for routine and analytical laboratory use.

Calibrated to ISO 1042, this Class A flask includes a blue printed graduation with a finely diamond ground meniscus mark for defined visual alignment. The precision formed neck enables controlled filling to the calibration line, whilst the plastic stopper forms a secure, chemical resistant seal to protect your prepared solutions from contamination or evaporation. Each flask is batch certified to provide traceable calibration accuracy and help you meet quality assurance standards. Built for busy analytical labs, it maintains consistent volumetric performance through repeated use.
