Volumetric flask, 15 ml, class A with batch certificate, NS 10/19 joint and hexagonal hollow stopper is a precision measuring vessel made from borosilicate glass 3.3. This wide-neck flask in Diffico brown glass delivers accurate volumetric preparation for analytical chemistry, quality control and routine laboratory work. Each unit is marked with a batch number and supplied together with a batch certificate per original packaging, confirming conformity and supporting full traceability. The class A accuracy rating ensures reliable volume definition for standard solutions and quantitative assays. The NS 10/19 ground joint accepts the matching hexagonal hollow stopper for secure closure during mixing and storage. Manufactured from chemically resistant borosilicate glass 3.3, the flask combines thermal stability with mechanical robustness. The amber Diffico colouration helps protect light-sensitive contents. Offered in packs of 10 pieces from manufacturer Witeg, these volumetric flasks suit demanding laboratory environments where certified class A performance and documented batch control are required. Net weight is 0,024 kg per flask.

Questions about Volumetric flasks, 15 ml, A, CC, ST 10/19,
What is this article?
Volumetric flasks, 15 ml, A, CC, ST 10/19, 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.
