Description
Pellet burette 50 ml class AS with Schellbach stripe provides high-accuracy volumetric measurement for laboratory titration procedures. The instrument has a 50 ml capacity graduated at 0,1 ml intervals and complies with class AS requirements according to ISO 385. A Schellbach stripe is incorporated to facilitate clear meniscus observation and precise endpoint reading. This version is equipped with an NS intermediate stopcock together with a lateral stopcock fitted with an NS glass key. The complete assembly includes a 2 l reservoir bottle and is supplied without a pressure ball. Conformity certification (kb) confirms adherence to stated tolerances. Manufactured by Witeg, these pellet burettes are designed for Schilling-type rapid-operation titration systems commonly employed in analytical chemistry. Robust glass construction and calibrated scale support reproducible results. Net weight is 1,292 kg. Supplied as a pack of 2 pieces, the burette is well suited to quality-control laboratories and research environments requiring dependable class AS performance.

Questions about Automatic burette 50 ml class AS Schellbach
What is this article?
Automatic burette 50 ml class AS Schellbach is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Burettes, inside Volumetric glassware, in Matériel de laboratoire.
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.
