Description
Volumetric flask, PMP, class A, with NS stopper 12/21, PP, 50 ml is a precision measuring vessel for preparing and diluting solutions to a defined volume in analytical and routine laboratory work. The flask is made from polymethylpentene (PMP) and meets accuracy class A requirements for plastic volumetric ware. Its nominal volume is 50 ml (0,05 l), and the ground joint is sized NS 12/21. A matching polypropylene (PP) stopper closes the neck securely during inversion, mixing and short-term holding of prepared standards or reagents. Lightweight construction, with a gross weight of 0,011 kg, eases bench handling and reduces breakage risk relative to glass. This volumetric flask from manufacturer Vitlab supports solution preparation, titration workflows and general quantitative chemistry in research, industrial quality control and teaching laboratories. Clear PMP walls aid reliable meniscus reading, while the standardised NS joint ensures compatibility with common stoppers and accessories. Supplied as one piece, it integrates readily into existing volumetric sets that use NS 12/21 joints.

Questions about Volumetric flask, PMP, class A, 50 ml, with stopper, NS 12/21, with ring-mark,
What is this article?
Volumetric flask, PMP, class A, 50 ml, with stopper, NS 12/21, with ring-mark, is the article on this page. Luminix Health distributes Vitlab for laboratory use. It sits in Fioles jaugées, inside Verrerie volumétrique, in Matériel de laboratoire.
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.
