Description
Volumetric flasks, class A, DURAN®, 100 ml are precision laboratory vessels intended for accurate preparation and dilution of standard solutions in volumetric analysis. Fabricated from transparent DURAN® glass, they combine a wide neck with a ground joint 14/23 for dependable stoppering during mixing and short-term holding of calibrated volumes. Class A tolerance supports consistent meniscus observation and reproducible results in analytical chemistry, quality control and everyday laboratory workflows. The wide neck eases filling, cleaning and transfer of liquids or powdered solids into the calibrated body. Offered as 2 pc(s) per pack from manufacturer Hirschmann, the unit weight is 0,156 kg. Clear glass construction permits straightforward visual checks of solution homogeneity and fill level at the graduation mark. These 100 ml flasks are well suited to chemical, pharmaceutical and environmental laboratories that rely on class A volumetric glassware for standard solutions, quantitative dilutions and routine assay preparation while retaining convenient handling and optical clarity.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, cl. A, DURAN®, 100 ml, joint 14/23, wide neck, transp. glass
What is this article?
Volumetric flasks, cl. A, DURAN®, 100 ml, joint 14/23, wide neck, transp. glass is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Matériel de laboratoire.
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.
