Description
Burette class AS with straight stopcock 10 ml is a precision volumetric glassware item intended for accurate titration work in analytical laboratories. Graduated 10:0,02 ml, it delivers class AS accuracy and is fitted with a straight stopcock incorporating a PTFE key for smooth, chemically resistant operation and reliable flow control. The clear-glass construction provides excellent visibility of the meniscus and titrant level, while the included calibration certificate (KB) documents conformity to the stated tolerance. Offered in a pack of 2 pieces, each unit has a net and gross weight of 0,07 kg, making the set convenient for bench use and storage. Produced by Witeg in Germany (Baden-Württemberg), these burettes meet the requirements of routine quantitative analysis, educational laboratories and quality-control environments where reproducible volume delivery is essential. The straight-stopcock design facilitates straightforward handling during titrations, and the PTFE key reduces the risk of seizing compared with traditional glass keys. Suitable for aqueous and many organic titrants, the burette supports precise endpoint determination in classical wet-chemistry methods.

Questions about Burette class AS straight stopcock 10 ml
What is this article?
Burette class AS straight stopcock 10 ml 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.
