Description
Volumetric flasks, class A, amber glass are precision laboratory vessels made from borosilicate glass 3.3 for accurate volumetric work. Each flask offers a nominal capacity of 250 ml and is fitted with a standard ground joint 14/23, supporting reliable preparation and storage of light-sensitive solutions in analytical and quality-control laboratories. The amber glass body helps protect contents from light while the class A tolerance supports demanding volumetric analysis, dilutions and standard preparations. Manufactured by Isolab, these flasks suit routine wet-chemistry workflows where reproducible volume measurement is essential. The borosilicate glass 3.3 construction provides the thermal and chemical resistance expected of laboratory glassware used with aqueous and many organic media. Supplied as a pack of 2 pc(s) with a total weight of 0,300 kg, the set is practical for bench stock or shared instrument rooms. Clear capacity marking and the standardised joint facilitate stopper compatibility and integration into existing glassware systems for titration, sample make-up and reference solution handling.

Questions about Volumetric flasks, cl. A, amber glass, borosilic. gl. 3.3, joint 14/23, 250 ml
What is this article?
Volumetric flasks, cl. A, amber 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 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.
