Description
Volumetric flasks class A in transparent glass are precision laboratory vessels for preparing standard solutions and performing volumetric analysis. These 25 ml flasks are made from borosilicate glass 3.3 and carry a ground joint 10/19, supporting accurate make-up to the mark and secure stoppering during mixing. Clear glass construction allows reliable meniscus reading and straightforward visual checks of contents throughout dilution and transfer steps. Offered as a pack of 2 pc(s) with a stated weight of 0,070 kg, the set fits everyday analytical benches in chemistry, quality control and teaching environments. Class A volumetric flasks from manufacturer Isolab combine the chemical resistance of borosilicate glass 3.3 with the volume accuracy required for reproducible laboratory work. The transparent body aids cleaning verification and residual-volume observation, while the defined joint geometry supports consistent sealing when solutions are shaken or stored briefly before use. Suitable for calibration standards, titrants and reference preparations where tightly controlled volume definition is essential in routine volumetric workflows.

Questions about Volumetric flasks class A Clear glass, 25 ml, 10/19
What is this article?
Volumetric flasks class A Clear glass, 25 ml, 10/19 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.
