Description
Volumetric flask BLAUBRAND® ETERNA Class A in borosilicate glass Boro 3.3 is a large-capacity precision vessel for accurate liquid measurement at the 2000 ml mark. Brown graduations improve legibility and are practical when handling light-sensitive samples or coloured solutions. The neck is finished with ground joint NS 29/32 and comes with a polypropylene stopper that seals the flask securely for mixing, equilibration or temporary holding of prepared media. Manufactured to Class A tolerances with DE-M marking, this flask from Brand includes an individual ISO certificate confirming volumetric accuracy. Robust Boro 3.3 construction delivers strong chemical resistance and solid thermal performance for demanding laboratory routines. It is well suited to analytical workflows, quality-control laboratories, process support and teaching labs where large calibrated volumes are prepared regularly. Applications include stock-solution make-up, dilutions and other volumetric tasks that require Class A glassware. Supplied as one piece for convenient single-unit ordering.

What is this article?
Vol. flask, BLAUBRAND-ETERNA, class A, 2000 ml, with NS 29/32 PP stopper, DE-M 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.
