Description
Burettes with Schellbach stripes, class B, serve as glass volumetric instruments for controlled titration and liquid delivery. Each burette is produced from DURAN® glass, features a straight valve cock, and holds 25 ml, a common working volume for routine analytical and educational titrations. The Schellbach stripe improves meniscus visibility against the liquid column, supporting clearer scale reading and reduced parallax under class B conditions. Straight valve-cock operation allows steady adjustment of flow during acid–base, redox and complexometric procedures typical of quality-control and teaching labs. These burettes from manufacturer Hirschmann are packed as two pieces with a combined weight of 0,350 kg, suited to parallel bench use or spare capacity. They fit standard liquid-handling arrangements among glass burettes and titration apparatus, combining DURAN® glassware with Schellbach contrast for dependable everyday volumetric work where class B performance meets laboratory requirements.
This article is part of Burettes, in Volumetric glassware.

Questions about Burettes with Schellbach stripes, cl. B, DURAN®, straight valve cock, 25 ml
What is this article?
Burettes with Schellbach stripes, cl. B, DURAN®, straight valve cock, 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.
