Description
Class A volumetric flasks in amber glass serve as precision vessels for volumetric analysis, presented here at 50 ml nominal volume with ground joint 12/21. They are produced from borosilicate glass 3.3, combining class A volumetric accuracy with the durability expected of this glass grade in laboratory use. The amber glass body supports applications in which reduced light transmission is desirable while solutions are prepared or held at the calibration mark. Unit quantity is 2 pc(s) and the listed weight is 0,130 kg. Offered by manufacturer Isolab, this 50 ml flask is suited to quantitative laboratory practice, including preparation of standard solutions and other volume-critical steps in research, QC, and teaching environments. Defining attributes are class A amber borosilicate glass 3.3, joint 12/21, and the 50 ml capacity, providing a clearly specified mid-range option within the amber volumetric flask series for everyday analytical glassware requirements.
This article is part of Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, cl. A, amber glass, borosilicate gl. 3.3, joint 12/21, 50 ml
What is this article?
Volumetric flasks, cl. A, amber glass, borosilicate gl. 3.3, joint 12/21, 50 ml is the article on this page. Luminix Health distributes Isolab 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.
