Description
Volumetric flasks, class A, amber glass provide calibrated vessels for accurate volume measurement in the laboratory, here in a 100 ml format with ground joint 12/21. The flasks are made from borosilicate glass 3.3 and finished in amber glass to help shield light-sensitive contents during preparation and short-term holding of solutions. Class A designation corresponds to the tighter volumetric tolerance grade commonly specified for analytical standard solutions and quantitative dilutions. Joint 12/21 defines the neck interface for stoppers or closures matched to this size. Supplied in packs of 2 pc(s), with a unit weight of 0,180 kg, the ware is intended for volumetric analysis workflows that need both light protection and class A accuracy. These 100 ml amber volumetric flasks from manufacturer Isolab combine borosilicate glass 3.3 durability with the stated joint geometry, supporting everyday solution make-up, dilution series and volumetric measurement in research, teaching and quality-control settings where amber class A glassware is preferred.
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, 100ml
What is this article?
Volumetric flasks, cl. A, amber glass, borosilicate gl. 3.3, joint 12/21, 100ml is the article on this page. Luminix Health distributes Isolab for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Matériel de laboratoire.
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.
