Description
Volumetric flasks, DURAN®, clear glass with graduated neck are laboratory vessels for accurate volume measurement and preparation of solutions in volumetric analysis. Each flask has a nominal capacity of 25 ml and a graduated neck that supports filling to the calibration mark with clear visual control of the meniscus. The transparent DURAN® glass body allows straightforward inspection of contents during dilution, standard preparation and quantitative work. Supplied as 2 pc(s) per pack, the set is practical for parallel preparations or routine bench use. Unit weight is 0,086 kg. These volumetric flasks from manufacturer Hirschmann suit chemistry, quality-control and teaching laboratories that rely on clear laboratory glassware for reproducible liquid volumes. They integrate into standard labware inventories for solution make-up, volumetric analysis and related analytical procedures where a defined fill volume is required. The graduated-neck design and clear glass construction keep everyday volumetric tasks efficient and easy to monitor at the bench.

Questions about Volumetric flasks, DURAN®, clear glass, Graduated neck, 25 ml, 2 unit(s)
What is this article?
Volumetric flasks, DURAN®, clear glass, Graduated neck, 25 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.
