Description
Burette clear with straight stopcock and NS glass plug, 25 ml, is a complete class B volumetric glassware item for controlled liquid dispensing in titration. The 25 ml capacity is graduated at 0,05 ml intervals, providing the resolution needed for precise titrant delivery. A straight stopcock fitted with an interchangeable NS glass plug (Küken) allows fine flow regulation without PTFE components. Supplied as a pack of 2 pieces with a net weight of 0,068 kg, the burettes are ready for immediate laboratory use. This clear-glass burette from manufacturer Witeg is designed for classical analytical procedures in chemistry, pharmacy and related disciplines. Full-glass construction offers broad chemical compatibility and is often preferred for teaching environments or solvent systems where plastic seals are undesirable. Class B accuracy suits routine quantitative analyses and educational work. The transparent body and clear graduations enable reliable meniscus observation. Ideal for acid-base, redox and other wet-chemistry titrations in quality-control, research and training laboratories requiring durable, traditional glass burettes.

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