Description
Burettes with Schellbach stripes, class AS, are precision glass titration tools for controlled volumetric delivery in chemical analysis. This 50 ml model is produced from DURAN® glass and fitted with a side-mounted glass cock that regulates outflow during titration sequences. A Schellbach stripe along the scale improves contrast at the meniscus and helps operators take clear volume readings. Class AS accuracy is appropriate for quantitative laboratory work that demands reliable graduated glassware. Manufacturer Hirschmann supplies these burettes in packs of 2 pc(s), with a net weight of 0,400 kg per pack. The side glass stopcock arrangement leaves the front scale unobstructed and supports comfortable handling on the laboratory bench. They are suited to teaching laboratories, quality-control suites and research environments performing routine acid–base, redox or complexometric titrations. Combining DURAN® glass, Schellbach stripe marking and class AS grading, this 50 ml configuration offers a practical liquid-handling solution for standard volumetric procedures based solely on the stated construction and capacity details.

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