Description
Volumetric flasks, DURAN®, clear glass with graduated neck are laboratory vessels intended for precise volume definition in solution preparation and volumetric analysis. This 330 ml clear-glass design supports visual control of the liquid level and meniscus at the neck graduation during make-up of standard solutions, dilutions and analytical working solutions. The graduated neck helps operators approach the calibration mark in a controlled way, which is essential for reproducible concentrations in wet-chemistry workflows. Offered as a pack of 2 pc(s) with a stated weight of 0,360 kg, the flasks suit routine bench use in research, quality-control and teaching laboratories. DURAN® clear glass construction from manufacturer Hirschmann provides the transparency needed for content inspection while remaining compatible with common laboratory handling and storage practice. Typical applications include preparation of volumetric standards, sample dilution prior to titration or instrumental analysis, and general volumetric work where a defined 330 ml capacity and clear observation of the fill line are required. These flasks integrate readily into existing glassware sets used for volumetric analysis and everyday laboratory solution handling.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, DURAN®, clear glass, Graduated neck, 330 ml, 2 unit(s)
What is this article?
Volumetric flasks, DURAN®, clear glass, Graduated neck, 330 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.
