Description
Volumetric flasks, DURAN®, clear glass with graduated neck provide defined-capacity vessels for accurate preparation of solutions in analytical and general laboratory practice. The 350 ml clear-glass format allows straightforward visual monitoring of contents and meniscus position at the graduated neck when filling to the mark for standard solutions, dilutions and working reagents. Graduated-neck geometry supports careful approach to the calibration line, supporting consistent volumetric work across routine wet-chemistry tasks. Supplied in a pack of 2 pc(s) and weighing 0,358 kg according to the product data, the flasks are practical for everyday bench operations in research, quality control and training environments. Clear DURAN® glassware from manufacturer Hirschmann combines content visibility with the handling characteristics expected of laboratory volumetric flasks. Typical uses include make-up of volumetric standards, sample preparation ahead of titration or instrumental measurement, and other volumetric-analysis steps that call for a 350 ml nominal volume with an easily readable neck graduation. The flasks fit conventional laboratory glassware collections used for solution preparation and volumetric procedures.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, DURAN®, clear glass, Graduated neck, 350 ml, 2 unit(s)
What is this article?
Volumetric flasks, DURAN®, clear glass, Graduated neck, 350 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.
