Beschrijving
The DURAN® burette class B, 50:0,1 ml is a clear glass volumetric burette intended for precise titration and quantitative dispensing of larger titrant volumes. Black graduations with line division give clear meniscus readability during analytical measurements. Made from borosilicate glass 3.3, the instrument provides solid chemical resistance and good thermal durability for daily laboratory service. A straight valve stopcock fitted with a PTFE spindle allows controlled, grease-free flow and secure sealing. Compliant with DIN EN ISO 385, this class B burette fulfils established accuracy tolerances for routine volumetric analysis. The 50 ml nominal volume with 0,1 ml scale intervals is well suited to standard acid-base, redox and complexometric titrations requiring higher capacity. Supplied in a pack of 2 pieces, the burettes from manufacturer Hirschmann integrate easily into common titration apparatus used in quality-control, teaching and research environments. The robust clear-glass construction ensures consistent performance under typical laboratory conditions.
This article is part of Burettes, in Volumetric glassware.

Questions about BURETTES CL. B 50:0,1 ML, STR.VALVE STOPC., PTFE SPINDLE
What is this article?
BURETTES CL. B 50:0,1 ML, STR.VALVE STOPC., PTFE SPINDLE 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.
