Description
Volumetric flasks, class A, DURAN®, 20 ml are precision laboratory flasks for volumetric analysis and the preparation of defined solution volumes. Fabricated from DURAN® glass and equipped with ground joint 10/19, they support class A volume work in analytical and research settings. According to the product data, this 20 ml version is not compliant with DIN, which should be considered when matching glassware to method or accreditation requirements. Packs contain 2 pc(s) and weigh 0,070 kg, providing a convenient unit size for laboratory stocking. These flasks are from manufacturer Hirschmann and form part of a DURAN® volumetric range used for routine quantitative tasks. The 20 ml nominal capacity suits intermediate standards, dilutions, and sample make-up ahead of titration or instrumental measurement. Joint 10/19 geometry aids compatibility with matching stoppers and handling practices already established in the lab. Use this class A DURAN® flask where a 20 ml format is needed and DIN compliance is not mandatory for the intended volumetric application.

Questions about Volumetric flasks, cl. A, DURAN®, 20 ml, joint 10/19, not compliance with DIN
What is this article?
Volumetric flasks, cl. A, DURAN®, 20 ml, joint 10/19, not compliance with DIN 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.
