Description
DURAN® volumetric flask, class A, serves as a precision vessel for preparing and containing accurately defined solution volumes in volumetric analysis. This 20 ml flask displays blue graduation markings for reliable meniscus reading and is supplied with an individual certificate, supporting traceable class A accuracy in analytical documentation. Class A performance addresses the needs of quantitative chemistry, quality control, method validation, and teaching laboratories that depend on tight volumetric tolerances. The 20 ml capacity is appropriate for standard and working-solution preparation, serial dilutions, and sample adjustment ahead of titration or instrumental measurement. Delivered in a pack of 2 pc(s) with a weight of 0,148 kg, the flask is convenient for routine laboratory sets and storage. Blue graduation improves contrast and readability during filling to the mark. Available from manufacturer DWK Life Sciences as part of the DURAN® volumetric glassware portfolio. Well matched to industrial, academic, and research workflows that specify certified class A volumetric flasks for consistent, reproducible volume definition in everyday analytical practice.

Questions about DURAN®-volumetric flask, cl. A,, indiv. certific., 20 ml, blue graduation
What is this article?
DURAN®-volumetric flask, cl. A,, indiv. certific., 20 ml, 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.
