Description
Class A volumetric flasks in amber glass are calibrated laboratory vessels for precise volume measurement, supplied in a 25 ml nominal capacity with ground joint 10/19. Construction is borosilicate glass 3.3, delivering the accuracy class associated with class A volumetric flasks together with robust chemical resistance. Amber glass is used for the body, which is relevant when working with light-sensitive media during dilution, adjustment to the mark, or interim holding. The pack comprises 2 pc(s) and the weight is given as 0,070 kg. These flasks from manufacturer Isolab fit volumetric analysis workflows in analytical, industrial, and educational laboratories that require amber class A glassware at 25 ml. Core identifiers remain class A tolerance, amber borosilicate glass 3.3, joint 10/19, and the 25 ml volume, making this variant a straightforward choice for standard solution work and related quantitative procedures without extraneous claims beyond the stated specifications.
This article is part of Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, cl. A, amber glass, borosilicate gl. 3.3, joint 10/19, 25 ml
What is this article?
Volumetric flasks, cl. A, amber glass, borosilicate gl. 3.3, joint 10/19, 25 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.
