Description
Class B clear glass burette 100 ml with side stopcock and solid NS glass key is a volumetric glassware item designed for accurate titration and controlled reagent dispensing. The clear-glass body ensures excellent visibility of the meniscus and graduation scale, enabling precise volume determination. Built to accuracy class B, the burette is equipped with a lateral (side) stopcock and a solid NS glass key that together provide secure, adjustable flow control. Supplied as a pack of 2 pc(s) with a net weight of 0,126 kg, it is intended for everyday analytical work in research, quality-control and educational laboratories. The side-stopcock configuration from manufacturer Witeg offers convenient operation while the solid glass key contributes to long-term sealing reliability. Produced in Germany, this clear-glass burette supports standard acid-base, redox and complexometric titrations and withstands typical aqueous laboratory media. Its robust yet simple design promotes straightforward cleaning and handling in busy laboratory settings that rely on class-B volumetric accuracy.

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.
