Description
Burettes with Schellbach stripes, class B are DURAN® glass titration tools built for accurate volumetric work at the 50 ml scale. The Schellbach stripe runs behind the scale and heightens meniscus visibility, helping operators read delivered volumes more confidently during titration. A side-mounted valve cock allows smooth, controlled outflow of reagent while the burette stays clamped in position. Class B tolerance is appropriate for routine analytical tasks in chemical laboratories, environmental testing and educational settings where dependable glass burettes are needed. The larger 50 ml capacity supports titrations that require greater titrant volume without frequent refilling. Supplied in a pack of 2 pc(s) from manufacturer Hirschmann, the pair is ready for parallel or backup use on the bench. Approximate weight per unit is 0,385 kg. These instruments integrate into standard liquid-handling and titration apparatus setups and support clear, reproducible volume delivery for everyday quantitative procedures.
This article is part of Burettes, in Volumetric glassware.

Questions about Burettes with Schellbach stripes, cl. B, DURAN®, valve cock on the side, 50 ml
What is this article?
Burettes with Schellbach stripes, cl. B, DURAN®, valve cock on the side, 50 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.
