Description
Daffert burette 25 ml DIN-B 2-way stopcock Schellbach is a precision glass titration burette manufactured to DIN class B tolerances. The nominal capacity is 25 ml with a scale division of 0,05 ml, allowing fine volumetric delivery during titrations. It is fitted with a two-way stopcock featuring an NS glass key and incorporates the Schellbach stripe for improved meniscus reading. The design supports rapid and accurate dispensing in analytical chemistry workflows. Offered by manufacturer Witeg, this Daffert-type burette is supplied as a set of two pieces and is intended for routine laboratory titration, volumetric analysis and teaching applications where class-B accuracy and clear scale visibility are required. The combination of two-way stopcock functionality and Schellbach reading aid facilitates efficient, reproducible titrations in quality-control and research settings.

Questions about BURETTES,DAFFERT,DIN-B, 25 ML:0,05 TWO-
What is this article?
BURETTES,DAFFERT,DIN-B, 25 ML:0,05 TWO- is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Burettes, inside Verrerie volumétrique, 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.
