Description
Clear glass burettes with side stopcock and NS glass key, 10 ml, class B serve as practical volumetric instruments for controlled liquid delivery in titration and analytical laboratory work. These class B burettes feature a 10 ml capacity and a lateral stopcock fitted with an NS glass key, allowing convenient side-mounted flow control during dispensing. Constructed from clear glass, they provide unobstructed observation of the liquid level and any colour changes that mark the titration endpoint. Supplied in packs of 2 pieces from manufacturer Witeg, the burettes are well suited to everyday wet-chemistry tasks, teaching laboratories and routine analytical procedures. With a net weight of 0,086 kg they combine manageable handling characteristics with the durability expected of laboratory glassware. Typical uses include acid-base titrations, redox determinations and other volumetric analyses where class B accuracy meets the required precision. The side-stopcock design supports efficient operation and straightforward maintenance across common laboratory media.
This article is part of Burettes, in Volumetric glassware.

Questions about Burettes, class B, with lateral stopcock
What is this article?
Burettes, class B, with lateral stopcock 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.
