Description
Burettes with Schellbach stripes, class AS, are glass volumetric instruments designed for precise liquid dispensing in titration and analytical liquid handling. Constructed from DURAN® glass, each burette features a valve cock mounted on the side to allow smooth, controlled delivery of solutions during laboratory procedures. The nominal volume is 25 ml, a widely used capacity for standard titrations and reagent addition where intermediate working volumes are required. Schellbach stripes support confident scale reading by improving contrast at the meniscus. Class AS identifies the accuracy class of this series for quantitative work. These burettes from manufacturer Hirschmann integrate into titration apparatus setups and general glassware benches in research, teaching, and industrial quality laboratories. They are classified among glass burettes for liquid handling and titration applications. Packaging is 2 pc(s) with a combined weight of 0,400 kg, convenient for laboratory inventory and shared workstations. With DURAN® construction, side valve cock, Schellbach stripes, and class AS grading, this 25 ml format offers a practical precision burette option for everyday volumetric tasks that demand clear graduation and reliable stopcock performance.
This article is part of Burettes, in Volumetric glassware.

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