Description
Volumetric flasks with stopper, class B, are polypropylene (PP) vessels for preparing fixed 25 ml volumes in routine laboratory work. Each flask is fitted with a standard ground joint stopper also made of PP, supporting closed storage and reduced contamination risk during make-up and holding of solutions. Class B tolerance suits general analytical preparation, teaching exercises, and quality-control tasks where a defined nominal volume is required without glassware. The set is supplied as 2 pieces, giving a convenient pair for parallel standards, sample dilutions, or spare capacity on the bench. Manufactured by Vitlab, these PP volumetric flasks offer a lightweight, breakage-resistant alternative for aqueous and compatible media in everyday volumetric practice. The integrated PP ground-joint stopper matches the flask material for consistent chemical contact and simple handling. Use them to prepare calibration solutions, dilute concentrates to a marked volume, and store short-term working solutions under stoppered conditions. Clear class B and 25 ml designation help align the flasks with method requirements for plastic volumetric ware in teaching and routine laboratory settings.

Questions about Volumetric flasks with stopper, class B, PP, w. stand. ground joint of PP, 25 ml
What is this article?
Volumetric flasks with stopper, class B, PP, w. stand. ground joint of PP, 25 ml 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.
