Description
Universal titration apparatus Schellbach DIN-AS 25 ml with lateral valve stopcock and PTFE spindle is a precision glassware unit designed for accurate volumetric work in analytical laboratories. The apparatus features a 25 ml capacity with 0,05 ml graduation intervals and is classified as accuracy class AS, ensuring reliable delivery for quantitative titrations. A Schellbach stripe supports clear meniscus reading, while the lateral valve stopcock incorporates a PTFE spindle for smooth, chemically resistant operation and tight sealing. The set is conformity-certified and supplied complete with a 2 l reagent bottle; a pressure ball is not included. This configuration from manufacturer Witeg suits routine and standardised titration procedures where class AS performance and Schellbach readability are required. The unit is offered as a pack of two complete assemblies, providing convenient replacement or parallel-station use in teaching, quality-control and research environments that demand reproducible burette-style delivery without additional accessories.

Questions about UNIVERSAL AUTOMATIC BURETTES, 25 ML:0,0
What is this article?
UNIVERSAL AUTOMATIC BURETTES, 25 ML:0,0 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.
