Description
Burettes with Schellbach stripes, class AS, are precision glass titration instruments for accurate volumetric liquid handling. Each burette is produced from DURAN® glass, fitted with a straight glass cock and sized for a 10 ml working volume. The longitudinal Schellbach stripe runs behind the scale to sharpen meniscus contrast, supporting clear volume reading during titration. Class AS accuracy places these burettes among high-grade volumetric glassware used in quantitative analytical chemistry. Supplied as a pack of two pieces with a pack weight of 0,350 kg, they suit routine wet-chemistry benches, quality-control labs and teaching environments. The straight glass cock provides simple, chemically robust flow control that is straightforward to clean between series. From manufacturer Hirschmann, these glass burettes serve acid–base, redox and complexometric titrations and other liquid-handling tasks where reproducible delivery of titrant is required. Durable DURAN® construction and the Schellbach reading aid make them a practical choice for everyday laboratory titration work.

Questions about Burettes with Schellbach stripes, cl. AS, DURAN®, straight glass cock, 10 ml
What is this article?
Burettes with Schellbach stripes, cl. AS, DURAN®, straight glass cock, 10 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.
