Description
Burettes with Schellbach stripes, class B are glass titration instruments for precise volumetric delivery in laboratory liquid handling. These 25 ml units are made from DURAN® glass and carry a longitudinal Schellbach stripe that improves meniscus contrast against the graduation, supporting clearer volume readings during titration. A valve cock mounted on the side enables controlled release of titrant while the burette remains fixed in a stand. Class B accuracy suits routine quantitative work such as acid–base, complexometric and redox titrations in teaching, quality control and general analytical laboratories. The side-cock layout keeps the stopcock accessible for fine adjustment without obstructing the scale. Offered as a pack of 2 pc(s) from manufacturer Hirschmann, the set is intended for everyday bench use where reliable glass burettes are required. Each piece weighs about 0,350 kg. These instruments fit standard titration setups and support consistent volumetric practice across chemistry and environmental analysis workflows that depend on clear, repeatable volume measurement.
This article is part of Burettes, in Volumetric glassware.

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