Description
Class A volumetric flasks manufactured from transparent borosilicate glass 3.3 are laboratory vessels for precise volume measurement in volumetric analysis. This 250 ml flask is equipped with a ground joint 14/23 and supports preparation of standard solutions, controlled dilutions and quantitative transfer operations. Transparent walls permit clear observation of the liquid meniscus when adjusting to the calibration mark. The borosilicate glass 3.3 construction corresponds to the glass type widely used for analytical volumetric ware that must tolerate routine chemical contact. Pack size is 2 pieces, allowing concurrent sample work without frequent restocking of the bench. These volumetric flasks from manufacturer Isolab fit laboratory stoppers and accessories designed for the 14/23 joint. Weight is specified as 0,300 kg, aiding practical handling during weighing and solution preparation. They are intended for quality-control, research and educational laboratories that depend on class A volumetric glassware to establish accurate 250 ml volumes for titrimetry, reagent make-up and related analytical procedures.

Questions about Volumetric flasks, cl. A, transp. glass, borosilic. gl. 3.3, joint 14/23, 250 ml
What is this article?
Volumetric flasks, cl. A, transp. glass, borosilic. gl. 3.3, joint 14/23, 250 ml is the article on this page. Luminix Health distributes Isolab for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Matériel de laboratoire.
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.
