Description
DURAN® volumetric flask, class B is a large-capacity laboratory vessel for volumetric analysis and preparation of bulk standard solutions. This model offers a nominal capacity of 5000 ml and features white graduation for straightforward volume reading when adjusting to the calibration mark. Class B accuracy addresses general analytical, production-support and teaching needs where class B volumetric tolerances apply. The flask is supplied as 1 pc from manufacturer DWK Life Sciences and supports tasks such as large-volume solution make-up, dilution and quantitative transfer in chemical and life-science laboratories. White graduation provides contrast on the clear glass body to assist meniscus observation. At a weight of 1,505 kg, the unit is designed for stable placement on the bench during filling and mixing operations. It belongs to the volumetric-flask category used for volumetric analysis and complements other DURAN® glassware in research, industrial QC and educational settings that require a dependable 5000 ml class B flask for everyday volumetric work.

Questions about DURAN®-volumetric flask, class B, 5000 ml, white graduation, 1 unit(s)
What is this article?
DURAN®-volumetric flask, class B, 5000 ml, white graduation, 1 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.
