Description
DURAN® volumetric flask with unground stopper seat NS 29/32, 3000 ml nominal capacity and without print is a precision laboratory vessel for accurate volume measurement and solution preparation. Manufactured from borosilicate glass 3.3, it combines chemical resistance with thermal stability for everyday analytical work in research, quality-control and teaching laboratories. The unground NS 29/32 stopper seat accepts a matching stopper for secure closure during mixing or storage. With a clear 3 l working volume and no printed markings, the flask offers an unobstructed surface that can be labelled as required by the user. Supplied as one piece, this item originates from manufacturer Duran/DWK Life Sciences and carries the registered DURAN® trademark. Typical applications include preparation of standard solutions, dilutions and volumetric analysis where larger batch volumes are needed. The robust borosilicate construction supports routine laboratory handling, heating and cleaning cycles while maintaining dimensional stability. Packaging volume is 0,015487 m³, facilitating efficient storage and transport within laboratory logistics systems.

Questions about DURAN® Volumetric flask, unground stopper bed 29/32, 3000 ml, without print
What is this article?
DURAN® Volumetric flask, unground stopper bed 29/32, 3000 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.
