Description
Volumetric flasks, class A, DURAN®, 25 ml provide calibrated glassware for precise volumetric analysis and preparation of standard solutions. Each flask is produced from transparent glass with a PE-stopper and ground joint 10/19 for dependable sealing during laboratory handling. Class A accuracy supports quantitative work in analytical and quality-control environments where the 25 ml nominal volume is routinely required. The pack contains 2 pc(s) and has a weight of 0,070 kg, offering a compact option for benches focused on laboratory glass, vessels and consumables. Clear transparent walls aid meniscus observation when bringing solutions to the mark. These volumetric flasks from manufacturer Hirschmann combine DURAN® glass with a PE-stopper closure suited to everyday dilution and make-up procedures. Joint 10/19 matches the supplied stopper so flasks can be inverted gently for mixing without unnecessary spillage. They fit naturally into volumetric flask workflows for research, teaching and routine analytical preparation at the 25 ml scale.

Questions about Volumetric flasks, cl. A, DURAN®, 25 ml, PE-stopper, joint 10/19, transp. glass
What is this article?
Volumetric flasks, cl. A, DURAN®, 25 ml, PE-stopper, joint 10/19, transp. 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.
