Description
DURAN® volumetric flask, class A, is a precision laboratory vessel for accurate preparation of standard solutions and volumetric analysis. This individually certified flask offers a nominal capacity of 200 ml with clear blue graduation markings that support reliable volume reading at the meniscus. Supplied as a pack of 2 pc(s) with a total weight of 0,420 kg, it is suited to routine quantitative work in chemical, pharmaceutical and teaching laboratories. Class A accuracy supports demanding titration workflows, dilution of stock solutions and preparation of calibration standards where reproducible volumetric measurement is essential. Blue graduation provides strong visual contrast for straightforward observation during filling and adjustment to the mark. Each unit is individually certified, documenting conformity to class A requirements and aiding traceable laboratory practice. From manufacturer DWK Life Sciences, the DURAN® flask integrates smoothly into classical wet-chemistry methods, quality-control protocols and method validation. It is intended for preparing defined concentrations, performing volumetric analysis and supporting everyday analytical procedures that rely on precise liquid measurement.

Questions about DURAN®-volumetric flask, cl. A,, indiv. certific., 200ml, blue graduation
What is this article?
DURAN®-volumetric flask, cl. A,, indiv. certific., 200ml, 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.
