Description
Volumetric flasks, class A, transparent glass are precision labware for accurate solution preparation and volumetric analysis. Fabricated from borosilicate glass 3.3, they provide chemical resistance together with clear visibility of the liquid level. The flasks feature a ground joint 10/19 and a nominal volume of 20 ml, addressing common mid-range capacities used in standardisation, dilution series and quantitative assays that require class A tolerance. Clear glass construction aids reliable meniscus reading during make-up to volume. Delivered as a pack of two pieces with a unit weight of 0,070 kg, these vessels from manufacturer Isolab are suited to analytical chemistry, quality control and instructional laboratories. Their defined joint geometry and class A rating support reproducible volumetric practice with durable, transparent borosilicate glassware.
This article is part of Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks class A Clear glass, 20 ml, 10/19
What is this article?
Volumetric flasks class A Clear glass, 20 ml, 10/19 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.
