Description
Volumetric flask 1000 ml DIN-A without stopper is a medium-neck laboratory flask engineered for precise volumetric measurements. It is fitted with an NS 29/32 ground joint, complies with DIN Class A specifications and includes a conformity certificate. A permanent ring mark and content indication are provided, together with a ground stopper seat; the stopper itself is not supplied. The flask is finished in DIFFICO brown glass, offering protection for photosensitive solutions. Produced by manufacturer Witeg, these measuring flasks support accurate preparation of standard solutions, dilutions and analytical procedures that require Class A tolerance. Each flask has a net weight of 0,272 kg. Supplied in packs of 10 pieces, the set enables laboratories to maintain a ready stock of identically calibrated vessels. The medium-neck design simplifies handling and mixing operations while the brown DIFFICO surface helps preserve the integrity of light-sensitive contents during storage and use in routine quantitative work.

Questions about Volumetric flask, 1000 ml, ST 29/32, DIN
What is this article?
Volumetric flask, 1000 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.
