Description
DURAN® volumetric flask, class A, provides a reliable vessel for precise volume definition when preparing standards, dilutions, and assay solutions. This 5 ml model features blue graduation for straightforward meniscus reading and includes an individual certificate to support traceable volumetric performance in regulated and research settings. Class A accuracy meets the demands of quantitative analytical chemistry, quality-control laboratories, and method development where small working volumes must remain reproducible. The 5 ml capacity is well suited to intermediate-scale preparations, calibration standards, and sample adjustment prior to instrumental analysis. Supplied as 2 pc(s) with a weight of 0,068 kg per unit data, the flask fits compact storage and routine bench use. Blue graduation markings improve visibility against colourless or lightly coloured liquids under standard laboratory illumination. From manufacturer DWK Life Sciences, DURAN® volumetric flasks are established tools within volumetric analysis glassware ranges. Ideal for teaching labs, industrial QC, and research groups that specify certified class A flasks for consistent volumetric work across repeated preparations and titrations.

Questions about DURAN®-volumetric flask, cl. A,, indiv. certificate, 5ml, blue graduation
What is this article?
DURAN®-volumetric flask, cl. A,, indiv. certificate, 5ml, blue graduation 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.
