Description
Burette AS 25 ml with Schellbach stripe and PTFE plug KB is a precision volumetric glassware item designed for accurate titration work in analytical laboratories. It offers a nominal capacity of 25 ml with 0,05 ml graduation intervals and is manufactured to class AS tolerance for high volumetric accuracy. The straight stopcock features a PTFE spindle for smooth, chemically resistant operation and reliable sealing during titrations. A Schellbach stripe runs along the tube to improve meniscus readability and reduce parallax error when reading volumes. Supplied as a set of two pieces with a net weight of 0,078 kg each, this burette supports routine quantitative analysis, acid-base titrations and other volumetric procedures. The robust construction from manufacturer Witeg ensures consistent performance in daily laboratory use. Ideal for teaching labs, quality-control environments and research settings that require class AS glassware with PTFE components for chemical compatibility.

Questions about Burettes, 25 ml 0,05 class-AS, with str
What is this article?
Burettes, 25 ml 0,05 class-AS, with str 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.
