Description
Volumetric flask, class A, DURAN®, 2000 ml is a precision laboratory vessel for accurate preparation and dilution of standard solutions in volumetric analysis. Manufactured from amber DURAN® glass, it helps protect light-sensitive media while the class A rating supports high-accuracy volume work in analytical and quality-control laboratories. The flask is fitted with a PE stopper and a standard ground joint 29/32, giving a secure closure during mixing, storage, and transfer steps. With a nominal capacity of 2000 ml, this single-piece unit suits larger batch preparations, stock solutions, and routine volumetric workflows where reproducible fill-to-mark performance is essential. Supplied as 1 pc(s) from manufacturer Hirschmann, the flask weighs 0,560 kg and integrates readily into glassware sets used for titration, assay preparation, and general wet-chemistry procedures. Amber colouration supports handling of photosensitive reagents, while the PE stopper offers convenient, chemically resistant sealing for everyday laboratory use. Ideal for teaching labs, research benches, and industrial analytical suites that rely on class A volumetric glassware for dependable volume definition.

Questions about Volumetric flask, cl. A, DURAN®, 2000 ml, PE-stopper, joint 29/32, amber glass
What is this article?
Volumetric flask, cl. A, DURAN®, 2000 ml, PE-stopper, joint 29/32, 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.
