Description
Volumetric flasks with stopper, class B are crystal-clear laboratory vessels made from polymethylpentene (PMP) for accurate preparation of defined liquid volumes. This variant has a nominal capacity of 25 ml and a standard ground joint of size 10/19 closed by a polypropylene (PP) stopper. Supplied as a pack of 2 pieces from manufacturer Vitlab, the flasks suit routine volumetric analysis, standard-solution preparation and controlled dilutions in research, quality-control and teaching laboratories. PMP offers high transparency with a lightweight, chemically practical body for everyday bench use. Class B accuracy meets general analytical tasks where class A tolerances are not required. The ground joint with matching PP stopper supports a secure closure during mixing and short-term holding of prepared solutions. Clear walls allow reliable meniscus observation at the calibration mark. The compact 25 ml format is convenient for small-volume standards, limited samples and instructional work, fitting smoothly into common volumetric plasticware sets.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks class B crystal clear, 25 ml, 10/19
What is this article?
Volumetric flasks class B crystal clear, 25 ml, 10/19 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.
