Description
Volumetric flask 1000 ml class A with batch certificate, NS 24/29 joint and PE stopper in USP amber glass delivers accurate volumetric work for light-sensitive samples under USP requirements. Produced from borosilicate glass 3.3, the flask combines high chemical durability with thermal shock resistance ideal for standard solution preparation. The amber glass protects contents from light while white Diffico markings remain clearly legible. Every unit is marked with a batch number and accompanied by a batch certificate in the original packaging, verifying class A conformity. The NS 24/29 ground joint pairs with the PE stopper to ensure tight sealing during handling and storage. Supplied in packs of 10 pieces from manufacturer Witeg, these USP-compliant flasks support pharmaceutical, analytical and quality-control laboratories that demand both volumetric precision and light protection. The sturdy design withstands routine laboratory cleaning and sterilisation procedures while retaining calibration integrity.

Questions about Volumetric flasks, 1000 ml, A, CC, ST 24/29,
What is this article?
Volumetric flasks, 1000 ml, A, CC, ST 24/29, 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.
