Description
Burette class B 10 ml brown glass with straight stopcock and PTFE key is a volumetric glassware item for controlled liquid delivery in laboratory titration and quantitative analysis. The brown glass body helps shield light-sensitive reagents during handling and measurement, while the straight stopcock fitted with an NS-PTFE key provides smooth, chemically resistant operation for routine dispensing. With a nominal capacity of 10 ml and class B accuracy, this burette supports everyday volumetric work in analytical chemistry, quality control and teaching laboratories. The PTFE key offers reliable sealing and straightforward maintenance compared with conventional glass keys. Produced by manufacturer Witeg, the instrument is intended for professional laboratory environments where class B performance is sufficient for standard titration protocols. Each unit has a net weight of 0,066 kg and is supplied in a pack of 2 pieces. Suitable for aqueous solutions and many common laboratory reagents, the design facilitates clear reading of the meniscus and consistent delivery during successive titrations. Ideal for educational settings and industrial labs performing repetitive volumetric determinations that require durable brown-glass construction and a PTFE-equipped stopcock.

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.
