Description
Volumetric flask 3000 ml, Class A, conformity-certified (KB), with NS 29/32 joint and PE stopper is a precision laboratory vessel intended for accurate volumetric work. Manufactured from borosilicate glass 3.3 in Diffico brown finish, it combines chemical durability with good thermal properties for everyday analytical use. The brown glass helps protect light-sensitive solutions during preparation and storage of standards. Supplied by manufacturer Witeg, each flask carries a batch number and is delivered with a batch certificate per original packaging, supporting full traceability. The polyethylene stopper seals the NS 29/32 ground joint securely. With its 3000 ml capacity this flask is well suited to larger-scale solution preparation, dilutions and quantitative assays in chemical, pharmaceutical and research laboratories that require Class A tolerances. Robust construction and documented conformity make it a practical choice for regulated and routine laboratory environments. Pack size is 1 piece.

Questions about Volumetric flask, 3000 ml, A, CC, ST 29/32, PE
What is this article?
Volumetric flask, 3000 ml, A, CC, ST 29/32, PE 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.
