Description
Volumetric flasks class A in transparent glass provide precise vessels for standard solution preparation and volumetric analysis at the 50 ml scale. Fabricated from borosilicate glass 3.3 with a ground joint 12/21, they support accurate filling to the calibration mark and dependable stopper fit during homogenisation. The clear glass wall enables confident meniscus observation and simple visual inspection of solutions throughout dilution and transfer. Supplied in packs of 2 pc(s) and listed at 0,150 kg, these flasks integrate smoothly into analytical, quality-control and instructional laboratory routines. Class A volumetric flasks from manufacturer Isolab unite borosilicate glass 3.3 durability with the volume tolerance expected for reproducible volumetric work. Transparent construction helps confirm cleanliness and residual liquid levels, while the specified joint size promotes secure closure when contents are mixed or held briefly before use. Well suited to preparing calibration standards, titrants and reference solutions that demand tightly controlled volume definition in day-to-day laboratory practice.

Questions about Volumetric flasks class A Clear glass, 50 ml, 12/21
What is this article?
Volumetric flasks class A Clear glass, 50 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.
