Mixing cylinder 250 ml class B high form NS 29/32 with PE stopper and hexagonal foot is a high-form laboratory vessel for accurate liquid mixing and volumetric work. Graduated at 2 ml intervals over the full 250 ml capacity, it offers a class B tolerance of ± 2 ml. The cylinder is manufactured from borosilicate glass 3.3 and finished in Diffico brown, combining chemical resistance with suitability for light-sensitive samples. A stable hexagonal foot keeps the vessel upright on the bench, while the NS 29/32 ground joint accepts the supplied polyethylene stopper for secure closure during shaking or short-term storage. Produced by manufacturer Witeg in accordance with DIN ISO 4788, this mixing cylinder supports routine analytical, quality-control and teaching applications that require reliable class B performance. The robust glass construction withstands everyday laboratory handling. Supplied in packs of 10 pieces, each unit has a net weight of 0,216 kg, making the format practical for equipping multiple workstations.
This article is part of Mixing cylinders, in Volumetric glassware.

Questions about Graduated cylinder 250 ml class B tall form
What is this article?
Graduated cylinder 250 ml class B tall form is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Mixing cylinders, inside Volumetric glassware, in Labmateriaal.
A mixing cylinder is a graduated cylinder with a stopper, so a dilute solution can be shaken in the vessel it was measured in. It is coarser than a volumetric flask and more convenient when many dilutions are made by hand.
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.
