Description
Volumetric flask, PMP, class B, 500 ml with NS 19/26 ground joint and PP stopper is a transparent laboratory flask designed for the accurate preparation of larger standard solutions and volumetric work. Fabricated from polymethylpentene, it delivers high optical clarity for precise meniscus reading along with chemical resistance appropriate for aqueous media and numerous common solvents. Class B tolerance is adequate for everyday analytical tasks, educational use and quality-control routines. The 500 ml nominal capacity and NS 19/26 joint accept the supplied polypropylene stopper, providing a secure closure for mixing and short-term holding. Offered by manufacturer Brand in packs of two pieces, the lightweight yet robust PMP body lowers breakage risk relative to glass while remaining convenient to handle. These flasks support dilutions, titrations and bulk sample preparation in teaching laboratories, industrial QC departments and research environments requiring reliable larger-volume plastic volumetric glassware.

Questions about Volumetric flask PMP class B, 500 ml, NS 19/26, PP-stopper, trans.
What is this article?
Volumetric flask PMP class B, 500 ml, NS 19/26, PP-stopper, trans. 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.
