Burettes, class B, SB 50:0,1 ml are precision volumetric instruments for accurate titration and quantitative analysis in analytical laboratories. These DURAN® burettes are manufactured from borosilicate glass 3.3 and carry blue graduation markings with a scale division of 0,1 ml and a nominal volume of 50 ml (0,05 l). A Schellbach stripe improves meniscus readability, while the straight glass stopcock provides controlled delivery. The design conforms to DIN EN ISO 385 and meets class B accuracy requirements for routine laboratory work. Supplied in packs of 2 pieces from manufacturer Hirschmann, the burettes are well suited to acid-base titrations, redox determinations and other volumetric procedures. The chemically resistant borosilicate construction offers good thermal stability and durability under everyday laboratory conditions, supporting reliable results in teaching, quality-control and research environments where class B performance is specified.
This article is part of Burettes, in Volumetric glassware.

Questions about BURETTES CL. B SB 50:0,1 ML, STRAIGHT STOPCOCK
What is this article?
BURETTES CL. B SB 50:0,1 ML, STRAIGHT STOPCOCK is the article on this page. Luminix Health distributes Hirschmann 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.
