Description
Burettes with Schellbach stripes, class AS, provide larger-capacity glass burettes for titration and controlled volumetric delivery. Made from DURAN® glass and equipped with a side-mounted valve cock, they enable steady stopcock operation when dispensing titrants or other liquids. The nominal capacity of 50 ml suits procedures that require greater working volume while retaining class AS accuracy grading. Schellbach stripes along the scale assist meniscus visibility and consistent volume assessment during use. This configuration supports analytical chemistry, process control, and teaching laboratories that rely on glass burettes within titration apparatus and liquid-handling workflows. Offered by manufacturer Hirschmann, the instruments combine durable DURAN® construction with a practical side valve layout for bench-top titration stands. Each pack comprises 2 pc(s) and weighs 0,400 kg, facilitating storage and distribution across laboratory stations. For applications needing a 50 ml class AS burette with Schellbach stripes and a side valve cock, these DURAN® units deliver a clear, serviceable option for quantitative liquid addition without unnecessary complexity in daily volumetric practice.
This article is part of Burettes, in Volumetric glassware.

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