Description
Class A volumetric flasks in transparent borosilicate glass 3.3 deliver defined volumes for accurate volumetric analysis and solution preparation. This 500 ml model uses a ground joint 19/26 and is intended for making up larger standard solutions, performing dilutions and completing quantitative transfers to a fixed volume. The transparent glass body allows unambiguous meniscus reading at the calibration line during filling. Borosilicate glass 3.3 is the specified material, consistent with laboratory glassware chosen for chemical resistance in analytical settings. Supplied as 2 pieces per pack, the flasks facilitate parallel preparation of multiple solutions. These volumetric flasks from manufacturer Isolab accept stoppers and fittings matched to the 19/26 joint size common in medium-capacity glassware. Weight is given as 0,450 kg, remaining practical for bench and balance handling. They suit research, quality-control and teaching laboratories that require class A volumetric glassware for reliable 500 ml volumes in titrations, reagent formulation and other quantitative workflows based on volumetric analysis.
This article is part of Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, cl. A, transp. glass, borosilic. gl. 3.3, joint 19/26, 500 ml
What is this article?
Volumetric flasks, cl. A, transp. glass, borosilic. gl. 3.3, joint 19/26, 500 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.
