Description
Burettes with Schellbach stripes, class B, are glass titration instruments for volumetric liquid handling in analytical laboratories. Each unit is made from DURAN® glass, carries a longitudinal Schellbach stripe for clearer meniscus contrast, and is fitted with a straight glass cock for controlled delivery. The 25 ml capacity suits routine acid–base, redox and complexometric titrations in quality control, research and teaching environments where class B accuracy is appropriate. The Schellbach stripe helps reduce parallax error and supports reproducible volume reading along the graduated scale during endpoint determination. These burettes from manufacturer Hirschmann are offered as a practical pack of two pieces with a combined weight of 0,350 kg, convenient for parallel setups or bench reserve. Straight glass-cock construction supports steady flow adjustment typical of classical burette work with aqueous and many common laboratory solutions. They fit standard liquid-handling workflows among glass burettes and titration apparatus, giving laboratories dependable class B glassware for everyday volumetric analysis without unnecessary complexity.
This article is part of Burettes, in Volumetric glassware.

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