Description
Schellbach burette 25 ml:1/20 with side stopcock, class AS is a volumetric glassware item intended for accurate liquid measurement and delivery during laboratory titration and related analytical procedures. The integrated Schellbach stripe aids clear meniscus observation and reduces reading error at the finer 1/20 graduation. Side-mounted stopcock geometry permits controlled reagent release from the lateral position. Supplied as one piece, the class AS designation denotes higher accuracy suited to demanding volumetric work. This burette from manufacturer Starke fits titration setups and specialised apparatus commonly employed in chemical, pharmaceutical and educational laboratories. The 25 ml capacity is convenient for determinations that require both fine scale division and reliable handling. Construction follows classic Schellbach principles, supporting routine quality-control measurements, standardisations and serial analyses where precise dispensing and easy readability are essential in research or teaching environments.

Questions about Burette/Schellbach 25 ml:1/20, with side stopcock, cl. AS
What is this article?
Burette/Schellbach 25 ml:1/20, with side stopcock, cl. AS is the article on this page. Luminix Health distributes Starke 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.
