Description
Volumetric flasks, class A, transparent glass are precision vessels for accurate preparation of standard solutions and volumetric analysis. Manufactured from borosilicate glass 3.3, they combine chemical resistance with thermal stability suitable for routine laboratory work. Each flask features a ground joint 10/19 and a wide neck design that simplifies filling, mixing and cleaning while the clear glass body allows easy observation of the meniscus and contents. The nominal capacity is 5 ml, supporting small-volume dilutions and calibrations where class A tolerance is required. Supplied as a pack of two pieces with a unit weight of 0,050 kg, these flasks from manufacturer Isolab fit standard stoppers and laboratory workflows for quantitative chemistry, quality control and teaching laboratories. Their transparent construction and defined joint geometry support reproducible volumetric work without unnecessary complexity.
This article is part of Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, cl. A, transp. glass, borosilic. 3.3, joint 10/19, 5 ml, wide
What is this article?
Volumetric flasks, cl. A, transp. 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.
