Description
Burette 25 ml DIN-AS Schellbach O+S+S is a precision glass volumetric instrument intended for accurate titration in analytical chemistry. It provides a 25 ml capacity with 0,05 ml graduation intervals according to DIN-AS requirements and is fitted with an olive, tubing and tip together with the characteristic Schellbach stripe. The Schellbach marking improves meniscus contrast and helps reduce reading errors during endpoint determination. Supplied in packs of 2 pc(s), each burette has a net and gross weight of 0,048 kg, making it convenient to store and handle on the laboratory bench. This configuration supports medium-volume acid-base, redox and complexometric titrations in teaching, research and quality-control laboratories. Produced by manufacturer Witeg in Germany, the burette meets established European standards for class AS volumetric glassware. The olive-hose-tip assembly allows straightforward connection to reservoirs or titration setups without extra adapters. Clear scale markings and the Schellbach feature together facilitate reliable volume delivery under typical laboratory lighting conditions.

Questions about Burettes, DIN-AS, 25 ml:0,05, Schellba
What is this article?
Burettes, DIN-AS, 25 ml:0,05, Schellba 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.
