Description
DURAN® volumetric flask with ground joint NS 29/32 and nominal volume of 2000 ml serves as a dependable large-capacity vessel for accurate solution preparation and volumetric measurement in laboratory environments. Manufactured from borosilicate glass 3.3, it offers excellent chemical resistance and thermal stability for everyday heating, cooling and autoclaving cycles. The pre-ground NS 29/32 joint provides a secure interface for matching stoppers and adapters, reducing the risk of leakage during mixing or storage. Supplied without print, the flask presents a clear, unobstructed view of the meniscus and contents, supporting precise volume determination. Available in packs of 10 pc(s) from manufacturer Duran/DWK Life Sciences, these flasks are particularly useful for preparing bulk standard solutions, large-scale dilutions and quantitative analyses in chemistry, life-science and industrial quality-control settings. The sturdy borosilicate construction withstands regular handling while preserving shape and accuracy over time. Transparent walls enable straightforward observation of colour shifts or separations, and the design accommodates a wide variety of aqueous and organic solvents. This DURAN® volumetric flask helps laboratories maintain reliable, reproducible results across demanding analytical and preparative workflows.

Questions about DURAN® Volumetric flask, partially ground, NS 29/32, 2000 ml, without print
What is this article?
DURAN® Volumetric flask, partially ground, NS 29/32, 2000 ml, without print is the article on this page. Luminix Health distributes DWK Life Sciences 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.
