Description
Class B burette 50 ml with straight stopcock and NS PTFE plug, clear glass is a volumetric instrument designed for titration and precise reagent delivery in the laboratory. The burette has a 50 ml capacity and meets accuracy class B requirements for general analytical applications. Manufactured from clear glass, it offers good visibility of the liquid column and meniscus throughout the dispensing process. The straight stopcock is equipped with an NS PTFE plug, combining controlled flow with the chemical resistance typical of PTFE sealing surfaces. These units from manufacturer Witeg come in a pack of 2 pieces and are appropriate for routine titrations, educational use and quality-control environments that accept class B tolerances. Clear glass construction supports standard acid-base and other aqueous titration procedures. Net weight is 0,088 kg, making the burette convenient for daily bench work. The design aligns with common laboratory practice for class B burettes used in volumetric analysis and titration apparatus assemblies.

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.
