Description
Class B burettes 25 ml brown glass with straight stopcock and PTFE plug provide reliable volumetric delivery for titration and analytical work in research and quality-control laboratories. The brown-glass body shields light-sensitive reagents, while the straight stopcock equipped with a PTFE plug offers smooth, chemically resistant operation and reduced risk of seizing compared with all-glass assemblies. Rated to class B accuracy, these burettes meet the requirements of routine quantitative analysis without the tighter tolerances of class A instruments. Available in packs of 2 pc(s) from manufacturer Witeg, each burette weighs 0,07 kg net and is well suited to educational settings, industrial laboratories and general analytical workflows. The combination of amber glass and PTFE stopcock components ensures compatibility with a broad range of aqueous and organic titrants. Graduated to 25 ml capacity, the instruments allow clear volume observation during dispensing. These burettes constitute a practical solution for laboratories that require durable class B glassware with enhanced stopcock performance.
This article is part of Burettes, in Volumetric glassware.

Questions about Burettes class-B, with short line gradua
What is this article?
Burettes class-B, with short line gradua 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.
