Description
Volumetric flasks, class A, DURAN®, 500 ml are precision laboratory vessels designed for accurate preparation of larger standard solutions and for volumetric analysis. Constructed from transparent DURAN® glass, each flask is equipped with a PE-stopper and a ground joint 19/26 that provides a secure closure during dilution and mixing. The 500 ml nominal capacity combined with class A accuracy makes them suitable for quantitative procedures that demand reliable volume definition, including preparation of stock solutions, buffers and titrants. Clear glass walls support precise meniscus reading at the calibration mark. Offered as 2 pc(s) with a combined weight of 0,420 kg, the flasks come from manufacturer Hirschmann and serve analytical, quality-control and teaching environments. The larger joint size matches the higher volume format, while the polyethylene stopper simplifies repeated open-and-close cycles. Durable glass construction supports routine laboratory handling. These items form part of the established range of volumetric flasks and vessels used wherever controlled concentrations are required in chemical and related laboratory workflows.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, cl. A, DURAN®, 500 ml, PE-stopper, joint 19/26, transp. glass
What is this article?
Volumetric flasks, cl. A, DURAN®, 500 ml, PE-stopper, joint 19/26, transp. glass is the article on this page. Luminix Health distributes Hirschmann 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.
