Description
DURAN® automatic burette according to Pellet, class AS, with glass key, certificate of conformity and batch certificate is a precision volumetric assembly for titrimetric and volumetric analysis. The 10 ml burette is manufactured from chemically highly resistant borosilicate glass 3.3 and carries main-point ring graduation plus a Schellbach stripe for accurate meniscus observation. Adjustment is performed “Ex” (to deliver) at +20 °C reference temperature, so delivered volumes match the scale after allowance for liquid adhesion. A lateral NS stopcock and glass key control flow; waiting time is 30 seconds. The complete delivery comprises the burette, a 2000 ml reservoir bottle and a rubber blower for automatic filling. Class AS tolerances correspond to ISO and DIN error limits; the batch certificate records mean value, standard deviation and issue date of the production lot and is also retrievable online. This automatic Pellet burette set from manufacturer Duran/DWK Life Sciences supports reliable measure analysis, titration and routine volumetric work where certified accuracy and integrated reservoir operation are essential.

Questions about DURAN® Automatic Burette, Class AS, Pellet-type, glass key, CoC, batch certifica
What is this article?
DURAN® Automatic Burette, Class AS, Pellet-type, glass key, CoC, batch certifica is the article on this page. Luminix Health distributes DWK Life Sciences 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.
