Volumetric flask 50 ml class A is a precision laboratory vessel manufactured from borosilicate glass 3.3 in amber glass for light-sensitive solutions. It features a ground joint NS 14/23 fitted with a PE stopper and white Diffico marking. Supplied conformity-certified with batch number and accompanying batch certificate per original packaging, this flask meets class A accuracy requirements for volumetric work. The amber glass construction protects contents from light while the robust borosilicate 3.3 material ensures chemical resistance and thermal stability in routine analytical procedures. Available in packs of 10 pieces with a net weight of 0,038 kg per flask, the design supports reliable preparation of standard solutions and quantitative dilutions. Produced by manufacturer Witeg, these flasks combine precise calibration with a practical PE stopper for secure sealing during storage and handling in pharmaceutical, chemical and quality-control laboratories.

Questions about Volumetric flasks, 50 ml, A, CC, ST 14/23,
What is this article?
Volumetric flasks, 50 ml, A, CC, ST 14/23, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Maatkolven, inside Volumetrisch glaswerk, in Labmateriaal.
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.
