Description
DURAN® volumetric flask, class A, is a high-capacity volumetric flask designed for accurate preparation of large-volume standard and working solutions. It offers a nominal capacity of 5000 ml with blue graduation for distinct reading of the calibration mark. Supplied with a batch certificate, the flask is intended for class A volumetric analysis where defined accuracy and documented batch data are required. The product is from manufacturer DWK Life Sciences and fits analytical, quality-control and research laboratories handling multi-litre preparations. Blue graduation supports precise meniscus observation when diluting or making solutions up to volume at the five-litre scale. Delivered as 1 pc with a stated weight of 1,505 kg, this unit suits benches and stores that need a single large class A flask rather than multi-packs. The 5000 ml format is appropriate for bulk standards, media-related volumetric work and other procedures that exceed typical one- and two-litre flasks. Use this DURAN® class A volumetric flask with batch certificate whenever high-volume, certified volumetric glassware is specified for reproducible laboratory results.

Questions about DURAN®-volum. flask, class A,, batch certif., 5000 ml, blue graduation
What is this article?
DURAN®-volum. flask, class A,, batch certif., 5000 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.
