Description
Volumetric flask with glass stopper NS 29/32 is a clear Class A measuring flask with a nominal capacity of 2000 ml, supplied in a pack of 6 pieces for larger-volume laboratory work. It supports accurate preparation and dilution of standard solutions, stock reagents and calibration media where a precisely defined two-litre volume is required. The NS 29/32 ground joint accepts the corresponding glass stopper, ensuring reliable closure when the flask is inverted or shaken to homogenise contents. Clear glass construction allows easy visual control of the liquid level and meniscus at the graduation mark. Class A designation denotes the higher accuracy class typically demanded in quantitative analytical chemistry, quality-control laboratories and regulated wet-chemistry methods. These flasks from manufacturer Dinkelberg are well suited to bulk standard preparation, multi-litre dilutions and general volumetric analysis at the two-litre scale. Six units per pack facilitate shared use across benches or parallel preparation of several solutions. Originating from the Czech Republic, they fit conventional laboratory glassware ranges that specify Class A volumetric flasks with glass stoppers and NS 29/32 joints.

Questions about Flask, volumetric with Glass stopper NS 29/32, clear, Class A, 2000ml, 6/PK
What is this article?
Flask, volumetric with Glass stopper NS 29/32, clear, Class A, 2000ml, 6/PK is the article on this page. Luminix Health distributes Dinkelberg 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.
