Description
Volumetric flask 2000 ml DIN Class A without stopper is a medium-neck laboratory flask engineered for accurate volumetric work in analytical chemistry. The flask features a ground joint of NS 29/32 and a precision-ground stopper seat, yet is delivered without a stopper so that laboratories can select their preferred closure. A permanent ring mark and clear content indication support reliable meniscus reading at the nominal 2000 ml volume. Produced in DIFFICO brown glass, the vessel shields light-sensitive reagents and solutions from photodegradation while meeting DIN Class A accuracy requirements and including a certificate of conformity. Available from manufacturer Witeg, each flask has a net weight of 0,39 kg and is offered in packs of 10 pieces. The medium-neck geometry eases filling, mixing and pipetting, making the flask well suited for preparation of standard solutions, dilutions and reference materials in quality-control, research and routine analytical laboratories that demand certified Class A volumetric glassware.

Questions about Volumetric flask, 2000 ml, ST 29/32, DIN
What is this article?
Volumetric flask, 2000 ml, ST 29/32, DIN 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.
