Description
DURAN® volumetric flask, class A, is a large-capacity volumetric flask for precise make-up of solutions in volumetric analysis. With a nominal volume of 2000 ml and blue graduation, it enables clear reading of the calibration line during dilution and final volume adjustment. The flask is supplied with a batch certificate and meets class A requirements for quantitative laboratory work. Manufactured by DWK Life Sciences, this DURAN® vessel supports analytical chemistry, quality control and research applications that demand certified volumetric accuracy at the two-litre scale. Blue graduation markings improve contrast on the glass body for reliable meniscus observation. The product is offered as a pack of 2 pc(s) with a stated weight of 1,160 kg, making it suitable for laboratories that prepare bulk standards or larger working solutions. Class A accuracy combined with batch certification helps maintain traceable volumetric practice across titration, calibration and solution-preparation workflows. Choose this 2000 ml DURAN® class A volumetric flask when batch-certified glassware at higher volume is required for reproducible analytical results.

Questions about DURAN®-volum. flask, class A,, batch certif., 2000 ml, blue graduation
What is this article?
DURAN®-volum. flask, class A,, batch certif., 2000 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.
