Description
Volumetric flask 10 ml, class A with batch certificate, NS 10/19 joint, hexagonal hollow stopper and USP compliance is a precision measuring flask produced from borosilicate glass 3.3. The Diffico brown amber glass and conformity-certified class A calibration deliver accurate small-volume measurements while meeting USP requirements. Every flask carries a batch number and is accompanied by a batch certificate per original packaging. The NS 10/19 ground joint works with the supplied NS hexagonal hollow stopper to ensure secure closure during preparation of standards, dilutions and quantitative assays. Made by Witeg, these USP-grade flasks combine the chemical resistance and thermal stability of borosilicate 3.3 glass with the documentation needed for regulated laboratory environments. The pack of 10 pieces, each weighing 0,017 kg net, provides a practical supply for pharmaceutical, analytical and quality-control workflows that demand both volumetric precision and USP conformity.

Questions about Volumetric flask, 10 ml, A, CC, ST 10/19,
What is this article?
Volumetric flask, 10 ml, A, CC, ST 10/19, is the article on this page. Luminix Health distributes Witeg 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.
