Description
Burette class B 25 ml with Schellbach stripe and lateral stopcock is a volumetric glass instrument intended for controlled liquid delivery in laboratory titration work. It provides a nominal capacity of 25 ml with 0,05 ml graduations and meets class B accuracy requirements for routine analytical measurements. The lateral stopcock is fitted with an NS glass plug that permits fine flow adjustment during titrant addition, while the longitudinal Schellbach stripe creates a clear optical reference for precise meniscus reading and reduced parallax. Supplied in a pack of 2 pc(s) and weighing 0,072 kg net, the burette is produced by manufacturer Witeg in Germany. It is suitable for acid-base, redox and complexometric titrations, solution standardisation and general quantitative wet chemistry in research, quality-control and teaching laboratories. The side-mounted stopcock arrangement supports convenient mounting on standard stands and allows ergonomic one-handed operation. The Schellbach design further assists consistent endpoint detection when working with colourless or lightly coloured solutions under typical laboratory lighting conditions.

Questions about Burettes class B 25 ml Schellbach lateral stopcock
What is this article?
Burettes class B 25 ml Schellbach 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.
