Description
Class AS burette 100 ml with PTFE spindle is a DIN class AS volumetric burette intended for accurate titration and controlled reagent delivery. The 100 ml working volume is subdivided at 0,2 ml, allowing fine adjustment of dispensed volumes during acid–base, redox, or complexometric titrations. A lateral valve stopcock with PTFE spindle provides chemical-resistant, smooth flow regulation and reliable shut-off at the bench. The Schellbach stripe supports clear meniscus reading and reduces parallax error when operators record intermediate or final volumes. Offered as one piece with a net weight of 0,115 kg, the burette integrates readily into standard titration stands and apparatus trains used in analytical, teaching, and quality-control laboratories. From manufacturer Witeg, the configuration combines DIN-AS classification, side-mounted valve geometry, PTFE spindle, and Schellbach stripe for everyday volumetric work. Typical application areas include general burette use, pellet burettes, rapid Schilling-type operation, and complete titration assemblies where reproducible class AS performance and PTFE-contact stopcock components are preferred.

Questions about Burettes DIN AS, 100 ml:0,2 with valve,
What is this article?
Burettes DIN AS, 100 ml:0,2 with valve, 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.
