Description
Volumetric flasks, class A, DURAN®, 5 ml are precision laboratory vessels for volumetric analysis and accurate preparation of standard solutions. Made from DURAN® amber glass, each flask is fitted with a PE-stopper and a ground joint 10/19 for secure closure during mixing and handling. The amber glass supports work with light-sensitive solutions, while class A accuracy meets demanding quantitative laboratory requirements. Supplied as a pack of 2 pc(s) with a pack weight of 0,050 kg, these flasks suit routine analytical tasks in research, quality control, and teaching environments. They are produced by manufacturer Hirschmann and belong to a practical DURAN® volumetric glassware range for everyday lab use. The 5 ml nominal capacity is convenient for small-volume standards, stock dilutions, and sample preparation ahead of titration or instrumental measurement. Clear class A marking and the NS 10/19 joint help integrate the flasks into existing volumetric workflows without changing established handling procedures. Choose this format when compact amber glassware with a polyethylene stopper is needed for reproducible class A volume work.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, cl. A, DURAN®, 5 ml, PE-stopper, joint 10/19, amber glass
What is this article?
Volumetric flasks, cl. A, DURAN®, 5 ml, PE-stopper, joint 10/19, 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.
