Description
Volumetric flasks, class A, amber glass are small-volume precision vessels made from borosilicate glass 3.3 for volumetric analysis of light-sensitive materials. Each flask offers a 5 ml capacity, a wide design and a ground joint 10/19, supporting accurate preparation of micro-scale standard solutions and quantitative dilutions. Amber glass helps limit light exposure to contents while the class A specification supports reliable volumetric work. Supplied as a pack of 2 pc(s) with a weight of 0,050 kg, the set is convenient for analytical benches handling small sample or reagent volumes. These flasks from manufacturer Isolab combine the chemical resistance of borosilicate 3.3 with amber protection and class A volumetric tolerances. They suit quality-control, research and teaching laboratories preparing light-sensitive solutions at low volume. The joint 10/19 accepts compatible stoppers for secure closure during mixing and short-term holding of prepared liquids.

Questions about Volumetric flasks, cl. A, amber glass, borosilic. 3.3, joint 10/19, 5 ml, wide
What is this article?
Volumetric flasks, cl. A, amber glass, borosilic. 3.3, joint 10/19, 5 ml, wide 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.
Which category should I open next?
