Description
Volumetric flasks class A in transparent glass serve as precision vessels for preparing standard solutions and conducting volumetric analysis at 100 ml. Made from borosilicate glass 3.3 with a ground joint 12/21, they enable accurate make-up to the mark and secure stoppering during mixing and short-term holding of solutions. Transparent walls support clear meniscus reading and straightforward visual inspection throughout dilution and transfer steps. Packaged as 2 pc(s) with a weight of 0,200 kg, these flasks suit regular use in chemistry, quality-control and educational laboratory settings. Class A volumetric flasks from manufacturer Isolab pair borosilicate glass 3.3 resistance with the volume accuracy required for consistent analytical results. The clear glass body assists cleaning verification and residual-volume checks, while the defined joint size promotes reliable sealing when contents are shaken or stored briefly. Ideal for calibration standards, titrants and reference preparations that depend on tightly controlled volume definition in everyday volumetric laboratory practice.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks class A Clear glass, 100 ml, 12/21
What is this article?
Volumetric flasks class A Clear glass, 100 ml, 12/21 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.
