Description
The volumetric flask BLAUBRAND® ETERNA, Class A, USP, 200 ml is a precision measuring flask for accurate preparation of volumetric solutions in analytical, pharmaceutical and quality-control laboratories. Made from borosilicate glass 3.3 (Boro 3.3), it offers chemical resistance and thermal durability for routine wet-chemistry work. The flask features an NS 14/23 ground joint and is supplied with a polypropylene (PP) stopper for secure closure during mixing and short-term storage of standards. Class A accuracy, USP compliance and DE-M marking support use in regulated environments, and each flask is accompanied by an individual USP certificate for documentation and traceability. Supplied as a single piece from manufacturer Brand, this BB-ETERNA volumetric flask is suited to dilution work, standard preparation and calibrated volume definition where exact meniscus reading is essential. Clear glass construction and a defined neck geometry aid precise volume adjustment, while the PP stopper provides a practical, chemically resistant seal for aqueous and many common laboratory media used in research and industrial labs.

Questions about Volumetric flask, BB-ETERNA, A, USP, 200 ml, Boro 3.3, NS 14/23, PP-stopper
What is this article?
Volumetric flask, BB-ETERNA, A, USP, 200 ml, Boro 3.3, NS 14/23, PP-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.
