Description
Volumetric flasks with stopper, class B are polypropylene (PP) laboratory vessels for volumetric analysis and the preparation of larger measured volumes. Each flask includes a standard ground joint of PP with stopper; the 250 ml format is specified with joint NS 19/26, supporting secure closure during inversion mixing and holding of defined solutions. Class B accuracy is appropriate for routine standard preparation, dilutions and general wet-chemistry tasks in quality control, teaching and research support labs. Transparent PP offers content visibility together with a lightweight, breakage-resistant body suited to many aqueous laboratory media. The products are supplied in packs of 2 pc(s), with an approximate weight of 0,165 kg, providing practical bench stock for higher-volume work. These volumetric flasks from manufacturer Vitlab complement other volumetric vessels used in chemical, environmental and life-science laboratories. Durable plastic construction, stopper convenience and clear 250 ml capacity help maintain reproducible liquid handling where class B polypropylene flasks are preferred over glass for robustness and ease of use.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks class B transparent, 250 ml, 19/26
What is this article?
Volumetric flasks class B transparent, 250 ml, 19/26 is the article on this page. Luminix Health distributes Vitlab 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.
