Description
Clear glass burette class AS 50 ml with straight stopcock is a precision volumetric glassware item intended for accurate liquid dispensing and titration in analytical laboratories. The instrument offers a nominal capacity of 50 ml with fine 0,1 ml graduations, supporting reproducible volume delivery under class AS accuracy requirements. A straight stopcock fitted with a glass plug enables controlled flow during titrations while the clear-glass body permits clear meniscus reading. This burette from manufacturer Witeg is supplied in a pack of 2 pc(s) and is suitable for routine acid-base, redox and complexometric work as well as teaching and quality-control environments. The class AS designation indicates compliance with the higher accuracy tier for volumetric glassware. Net weight is 0,094 kg. The combination of clear glass construction, straight glass-plug stopcock and 0,1 ml scale division makes the unit a practical choice for laboratories that require reliable, easily readable burettes for quantitative analysis without additional accessories.

Questions about Burette clear class AS 50 ml straight stopcock
What is this article?
Burette clear class AS 50 ml straight 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.
