Volumetric flask, 200 ml, class A with batch certificate, NS 14/23 joint and hexagonal hollow stopper is a precision laboratory vessel manufactured from borosilicate glass 3.3. Finished in Diffico brown glass, it supports accurate preparation of standard solutions and quantitative dilutions in analytical and quality-control laboratories. Every flask carries a batch number and is accompanied by a batch certificate included with each original packaging, ensuring conformity documentation and clear traceability. Class A accuracy provides the volumetric reliability needed for demanding measurement tasks. The NS 14/23 ground joint is paired with a hexagonal hollow stopper for secure sealing during mixing, equilibration and short-term storage. Borosilicate glass 3.3 offers high chemical resistance and good thermal performance under typical laboratory conditions. The amber Diffico tint assists in protecting light-sensitive media. Supplied in packs of 10 pieces from manufacturer Witeg, these flasks are intended for routine and high-precision volumetric work. Net weight is 0,088 kg per flask.

Questions about Volumetric flasks, 200 ml, A, CC, ST 14/23,
What is this article?
Volumetric flasks, 200 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.
