Description
Volumetric flasks with stopper, class B, are crystal-clear PMP vessels built for everyday volumetric work in analytical and general laboratories. Each unit carries a standard ground joint with a polypropylene stopper, providing a reliable seal during solution preparation, dilution and short-term holding of standards or samples. The nominal volume is 500 ml with a 19/26 joint, a convenient size for medium-scale make-up where class B accuracy is appropriate. The polymethylpentene body offers high transparency, reduced weight versus glass and solid chemical resistance for many aqueous and common laboratory media. These class B flasks from manufacturer Vitlab come as a pack of 2 pieces, which is practical for parallel runs, teaching benches or backup stock. They form part of the established plastic volumetric-flask offering used in volumetric analysis, QC dilution schemes and routine quantitative procedures. Pack weight is 0,240 kg, supporting easy handling, storage and transport within the lab.

Questions about Volumetric flasks class B crystal clear, 500 ml, 19/26
What is this article?
Volumetric flasks class B crystal clear, 500 ml, 19/26 is the article on this page. Luminix Health distributes Vitlab for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Labware.
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.
