Description
Volumetric flask 100 ml class A with NS 12/21 ground joint and hexagonal hollow stopper is designed for precise volumetric measurements and preparation of standard solutions in the laboratory. Made from borosilicate glass 3.3 with Diffico brown finish, it offers excellent chemical durability together with protection against light for sensitive samples. The flask is conformity certified; every piece carries a batch number and each original packaging includes a batch certificate for complete documentation. The NS-hexagonal hollow stopper ensures a secure, easy-to-use closure at the standard joint. Net weight is 0,062 kg. Supplied by manufacturer Witeg in packs of 10 pc(s), these flasks are well suited to analytical chemistry, quality-control laboratories, pharmaceutical work and research environments requiring class A accuracy. The combination of borosilicate glass 3.3 and the brown Diffico surface supports reliable performance under normal laboratory thermal and chemical conditions while maintaining volumetric precision over repeated use.

Questions about Volumetric flasks 100 ml, A, CC, ST 12/21,
What is this article?
Volumetric flasks 100 ml, A, CC, ST 12/21, is the article on this page. Luminix Health distributes Witeg 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.
