Description
Volumetric flasks, DURAN®, clear glass with graduated neck are laboratory vessels built for accurate volume definition in solution preparation and volumetric analysis. The 500 ml clear-glass design permits easy visual control of contents and meniscus alignment at the graduated neck when adjusting solutions to the calibration mark. Graduated-neck construction supports careful filling for reproducible standard solutions, dilutions and analytical working reagents in daily wet-chemistry practice. Packaged as 2 pc(s) with a stated weight of 0,426 kg, the flasks are appropriate for routine bench work in research laboratories, quality-control units and teaching environments. Clear DURAN® glass from manufacturer Hirschmann provides the visibility needed for confident meniscus reading and fits standard laboratory handling and storage routines. Typical applications cover preparation of volumetric standards, larger-volume sample dilutions ahead of titration or instrumental methods, and other volumetric-analysis tasks that require a 500 ml capacity with a graduated neck. These flasks integrate into conventional collections of volumetric flasks and vessels used for quantitative solution make-up and laboratory volumetric procedures.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, DURAN®, clear glass, Graduated neck, 500 ml, 2 unit(s)
What is this article?
Volumetric flasks, DURAN®, clear glass, Graduated neck, 500 ml, 2 unit(s) 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.
