Description
Volumetric flask, class A, transparent glass is a large-capacity precision vessel made from borosilicate glass 3.3 for volumetric analysis. With a nominal volume of 5000 ml and a ground joint 34/23, it supports accurate preparation of bulk standard solutions, stock dilutions and large-volume calibrated working solutions. The transparent glass body enables clear meniscus observation at the calibration mark and simple visual assessment of fill level and cleanliness. Supplied as 1 pc with a weight of 1,350 kg, this flask is suited to laboratories that regularly handle multi-litre preparations. The class A flask from manufacturer Isolab combines borosilicate glass 3.3 chemical resistance and thermal stability with the tolerances expected of high-accuracy volumetric glassware. It is appropriate for analytical chemistry, quality control and process laboratories needing dependable large-format volumetric vessels. The joint 34/23 accepts matching stoppers for secure closure during mixing and temporary holding of prepared solutions.

Questions about Volumetric flask, cl. A, transp. glass, borosilic. gl. 3.3, joint 34/23, 5000 ml
What is this article?
Volumetric flask, cl. A, transp. glass, borosilic. gl. 3.3, joint 34/23, 5000 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.
