Description
Class A volumetric flasks in DURAN® transparent glass with a 5 ml capacity provide defined volumes for analytical and preparative laboratory work. Each flask is fitted with a PE-stopper and a ground joint of 7/16, supporting secure closure during mixing, standing, and handling of prepared solutions. Transparent glass walls allow clear meniscus observation when filling to the calibration mark. These flasks are suited to volumetric analysis, preparation of standard solutions, dilutions, and related quantitative tasks in research, quality control, and teaching laboratories. Supplied as 2 pc(s) from manufacturer Hirschmann, the pack weighs 0,040 kg and is practical for bench use and stock keeping. The compact 5 ml format is useful for limited sample amounts and concentrated stocks that must be diluted to an exact volume. DURAN® transparent glass forms a durable vessel body for routine laboratory handling. Class A accuracy is the grade commonly specified for demanding volumetric procedures. The PE-stopper with joint 7/16 enables repeated opening and closing while protecting the calibrated capacity of the flask during everyday use.

Questions about Volumetric flasks, cl. A, DURAN®, 5 ml, PE-stopper, joint 7/16, transp. glass
What is this article?
Volumetric flasks, cl. A, DURAN®, 5 ml, PE-stopper, joint 7/16, 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.
