Description
Volumetric flasks, class A, transparent glass are precision laboratory vessels made from borosilicate glass 3.3 for accurate volumetric analysis. Each flask has a nominal capacity of 1000 ml and a ground joint 24/29, supporting reliable preparation of standard solutions, quantitative dilutions and calibrated working solutions. The transparent glass body allows clear observation of the meniscus at the calibration mark and straightforward visual checks of fill level and cleanliness. Supplied as a pack of 2 pc(s) with a weight of 0,730 kg, the set is practical for routine analytical and quality-control workflows. These class A flasks from manufacturer Isolab combine the chemical resistance and thermal behaviour of borosilicate glass 3.3 with the dimensional expectations of high-accuracy volumetric glassware. They suit chemistry, research and teaching laboratories that need dependable vessels for medium-scale solution preparation. The joint 24/29 accepts matching stoppers for secure closure during mixing and temporary holding of prepared solutions on the bench.

Questions about Volumetric flasks, cl. A, transp. glass, borosilic. gl. 3.3, joint 24/29
What is this article?
Volumetric flasks, cl. A, transp. glass, borosilic. gl. 3.3, joint 24/29 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.
