Description
Volumetric flasks, class A, DURAN®, 500 ml are amber-glass precision vessels for preparing and adjusting solutions to a defined volume in volumetric analysis. Each flask is class A rated, made from DURAN® amber glass and closed with a polyethylene (PE) stopper on a ground joint 19/26, combining accurate volume definition with light attenuation for sensitive media. The 500 ml capacity supports larger stock solutions, multi-step dilutions and batch standard preparation in analytical and quality-control settings. Supplied as 2 pc(s) per pack with a weight of 0,450 kg, the set is convenient for laboratory inventory. Manufactured by Hirschmann, these volumetric flasks present the familiar DURAN® amber body, PE stopper and joint 19/26 interface used in everyday volumetric work. They are appropriate wherever a class A 500 ml flask with light-protective glass and a secure PE closure is required for solution make-up, mixing to the mark and short-term holding prior to analysis or further processing.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, cl. A, DURAN®, 500 ml, PE-stopper, joint 19/26, amber glass
What is this article?
Volumetric flasks, cl. A, DURAN®, 500 ml, PE-stopper, joint 19/26, amber 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.
