Description
Volumetric flask BLAUBRAND® class A USP in amber glass is a precision measuring vessel for accurate preparation and dilution of solutions in analytical laboratories. This 20 ml flask is manufactured from borosilicate glass 3.3 and fitted with a standard ground joint NS 10/19 complete with glass stopper. The amber glass body helps protect light-sensitive reagents and samples during volumetric work. Class A accuracy, USP conformity and DE-M marking support demanding quantitative procedures, while each flask is supplied with an individual USP certificate documenting its calibration. From manufacturer Brand, the BLAUBRAND® design is established in pharmaceutical, chemical and quality-control environments where reliable volume measurement is essential. The 20 ml nominal capacity suits standard preparation, reference solutions and titrimetric workflows at intermediate scale. Durable Boro 3.3 construction offers chemical resistance and mechanical stability under typical laboratory conditions, and the glass stopper provides a secure closure between preparation and measurement steps.

A volumetric flask is calibrated to contain one volume at a reference temperature, with a single mark on a narrow neck. Class A is the tight tolerance. It is not a storage bottle and it is not for heating. The stopper is part of the calibrated article.
Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
