Description
Burettes class B 50 ml with removable PTFE stopcock are clear-glass volumetric instruments intended for precise titration work in analytical and quality-control laboratories. Each burette offers a 50 ml capacity with 0,1 ml graduation intervals and class B accuracy, supporting reliable volume delivery during routine assays. The detachable PTFE stopcock enables straightforward cleaning, maintenance and replacement without discarding the glass body, while the clear-glass construction allows unobstructed observation of the meniscus and titrant. Supplied as a pack of two pieces from manufacturer Witeg, these burettes suit educational settings, research laboratories and industrial QC environments where dependable class B performance is required. The compact net weight of 0,078 kg per unit facilitates easy handling on the bench. Ideal for aqueous and many organic titrants, the combination of glass barrel and inert PTFE stopcock provides chemical resistance and long service life under normal laboratory conditions.

Questions about Burettes, Klasse B, 50 ml:0,1, w. new
What is this article?
Burettes, Klasse B, 50 ml:0,1, w. new is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labware.
A burette delivers a measured volume through a stopcock, which is how a titration is read. Class A and class AS state the tolerance. The stopcock, glass or PTFE, and the volume of the burette are the choices. A dirty bore changes the delivered volume.
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.
