Description
Volumetric flasks, class A, DURAN®, 1000 ml are precision glass vessels for accurate preparation of litre-scale standard solutions and for volumetric analysis. Made from transparent DURAN® glass, the flask is fitted with a PE-stopper and a ground joint 24/29 that ensures a reliable seal while solutions are mixed and brought to the mark. The 1000 ml nominal capacity and class A rating support quantitative laboratory work requiring well-defined volumes, such as stock-solution preparation, buffers and larger reagent batches. Clear glass construction aids accurate meniscus observation at the calibration line. Supplied as 1 pc with a weight of 0,340 kg, this flask is available from manufacturer Hirschmann for analytical chemistry, quality-control and teaching applications. The larger joint format matches the one-litre body, and the polyethylene stopper allows convenient repeated access. Robust glass walls suit everyday bench handling. The product belongs to the established range of volumetric flasks and vessels used wherever controlled solution concentrations are essential in research, production support and laboratory practice.

Questions about Volumetric flasks,cl. A, DURAN®, 1000 ml, PE-stopper
What is this article?
Volumetric flasks,cl. A, DURAN®, 1000 ml, PE-stopper 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.
