Description
Burettes with Schellbach stripes, class AS, are precision glass titration instruments intended for accurate volumetric delivery in analytical laboratories. This 25 ml version is made from DURAN® glass and equipped with a glass cock mounted on the side for smooth, controlled dispensing during titration. The longitudinal Schellbach stripe enhances meniscus visibility against the graduated scale and supports consistent volume readings. Class AS grading meets requirements for quantitative analytical work where dependable accuracy is needed. From manufacturer Hirschmann, the articles are packed as 2 pc(s) with a net weight of 0,210 kg. Side glass stopcocks keep the scale face clear and facilitate bench-top handling in teaching, quality-control and research settings. Typical applications include acid–base, redox and complexometric titrations within liquid-handling workflows. DURAN® construction, Schellbach contrast marking and class AS tolerance together provide a robust glass burette configuration for everyday volumetric procedures, supplied ready for use with the integrated side cock and without further accessories specified in the product data.
This article is part of Burettes, in Volumetric glassware.

Questions about Burettes with Schellbach stripes, cl. AS, DURAN®, glass cock on the side, 25 ml
What is this article?
Burettes with Schellbach stripes, cl. AS, DURAN®, glass cock on the side, 25 ml is the article on this page. Luminix Health distributes Hirschmann 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.
