Description
DURAN® volumetric flask, class A, is an individually certified volumetric flask with a nominal capacity of 5 l and blue graduation. Designed for volumetric flasks and volumetric analysis, it supports preparation and measurement of larger defined solution volumes in the laboratory. Blue graduation marks the calibrated fill line for clear volume reading at the five-litre scale. The unit quantity is 1 pc, with a listed weight of 1,505 kg. This class A flask is available from manufacturer DWK Life Sciences as part of the DURAN® laboratory glass range and includes individual certification for analytical use. The 5 l capacity suits bulk standard preparation, dilution series and related volumetric procedures that require a certified class A flask of this size. Blue graduation helps operators locate the reference mark promptly during filling. The product is intended for research, teaching and industrial laboratories that specify DURAN® class A volumetric flasks with individual certification when working at the 5 l volume in routine volumetric analysis and solution-handling workflows.

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