Description
Volumetric flask BLAUBRAND® Class A USP, 5 ml, is a small-capacity precision flask manufactured from Boro 3.3 borosilicate glass for exact volume measurement in analytical laboratories. The flask meets Class A and USP specifications, includes DE-M conformity marking and is delivered with an individual USP certificate. It features a ground joint NS 10/19 closed by a glass stopper, providing a tight seal for mixing and short-term holding of prepared solutions. This BLAUBRAND® volumetric flask from manufacturer Brand is intended for preparation of standards, micro-scale dilutions and quantitative work where a defined 5 ml volume must be adjusted reproducibly to the calibration mark. The narrow neck supports clear meniscus observation, and the Boro 3.3 glass body is suitable for routine aqueous laboratory chemistry. Supplied as one piece, the compact 5 ml format fits sample-limited methods, reference solution make-up and teaching or QC benches that require Class A USP accuracy at low volume.

What is this article?
Volumetric flask, BLAUBRAND, A, USP, 5 ml, Boro 3.3, NS 10/19, glass-stopper is the article on this page. Luminix Health distributes Brand for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Labware.
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.
