Description
Pellet burette 25 ml class AS with Schellbach stripe is a high-capacity titration burette engineered for accurate volumetric analysis. Graduated 25 ml with 0,05 ml divisions, it complies with class AS requirements and carries a conformity certificate to ISO 385. The design omits an intermediate stopcock and instead features a lateral stopcock with NS glass plug (Küken), offering straightforward operation without a pressure ball. A continuous Schellbach stripe improves meniscus definition and reading precision. The burette is paired with a 2 l reservoir bottle for convenient reagent storage and continuous feed during extended titration series. Produced by Witeg, this pellet burette is intended for routine quantitative work in chemical, environmental and quality-control laboratories where larger titre volumes and class AS accuracy are needed. Clear scale markings and the Schellbach stripe support reliable endpoint detection across common analytical methods. Pack size is 2 pc(s).

Questions about Automatic burettes, pellet, class AS, 25
What is this article?
Automatic burettes, pellet, class AS, 25 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.
