Description
DURAN® volumetric flask, class B, is a laboratory volumetric vessel designed for preparing and measuring defined solution volumes in volumetric analysis. This 500 ml flask carries white graduation markings that facilitate reliable reading of the nominal volume during dilution and bulk standard preparation. It forms part of the DURAN® glassware range from manufacturer DWK Life Sciences and addresses routine analytical needs where class B volumetric flasks are specified. Supplied in a pack of 2 pc(s), the unit quantity suits laboratories that maintain ready stock for teaching, quality-control and general chemistry work. White graduation gives clear contrast on the flask body so the meniscus can be set to the mark with confidence. The pack weighs 0,880 kg, a figure useful for handling and storage planning when larger volumetric flasks are stored together. At 500 ml capacity, the flask supports higher-volume solution preparation, volumetric dilution and related procedures within laboratory glassware systems that use class B DURAN® volumetric flasks.
This article is part of Volumetric flasks, in Volumetric glassware.

Questions about DURAN®-volumetric flask, class B, 500 ml, white graduation, 2 unit(s)
What is this article?
DURAN®-volumetric flask, class B, 500 ml, white graduation, 2 unit(s) 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.
