Questions about Compact burette PTFE stopcock BB AS DE-M, 25 ml:0,05 ml, Boro 3.3, Schellbach
What is this article?
Compact burette PTFE stopcock BB AS DE-M, 25 ml:0,05 ml, Boro 3.3, Schellbach is the article on this page. Luminix Health distributes BRAND for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labmateriaal.
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.
