Description
Volumetric flask, PP, class B with NS stopper 12/21 is a 50 ml measuring flask for preparing and holding standard solutions and accurately diluted samples in everyday laboratory work. Manufactured from polypropylene (PP), the flask offers a lightweight, break-resistant alternative to glass while remaining suitable for many aqueous and routine analytical applications. Accuracy corresponds to class B, supporting volumetric preparation where this tolerance class is specified.
This article is part of Volumetric flasks, in Volumetric glassware.
The neck is fitted with a ground joint NS 12/21 and a matching polypropylene stopper, helping to limit evaporation and contamination during standing, mixing or storage of prepared volumes. The nominal volume is 50 ml (0,05 l), making the flask practical for buffer preparation, calibration solutions and general wet-chemistry tasks. Supplied as a single piece from manufacturer Vitlab, this Messkolben is intended for laboratories that prefer polymer volumetric ware with a defined joint size and class B performance for teaching, QC and routine analytical workflows.

Questions about Volumetric flask, PP, with stopper, PP, 50 ml, NS 12/21, with ring-mark
What is this article?
Volumetric flask, PP, with stopper, PP, 50 ml, 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.
