Description
Burettes class B DURAN® with 10:0,02 ml capacity are precision volumetric glassware intended for accurate titration work in analytical laboratories. Manufactured from borosilicate glass 3.3, these clear-glass burettes feature black graduation marks, line division and a straight glass stopcock, conforming to DIN EN ISO 385. The nominal volume of 10 ml with 0,02 ml scale intervals (20 µl) supports reliable delivery of titrant under class B tolerance. The DURAN® brand glass provides excellent chemical resistance and thermal stability for routine aqueous and many organic titrations. Supplied as a pack of 2 pieces, the burettes are ready for use in educational, quality-control and research settings. Straight glass stopcocks allow smooth, controlled flow without additional plastic components. These burettes from manufacturer Hirschmann combine traditional glass construction with clear, permanent black graduations for easy reading of meniscus levels. Ideal for acid-base, redox and complexometric titrations where class B accuracy is specified.

Questions about BURETTES CL. B 10:0,02 ML, STRAIGHT STOPCOCK
What is this article?
BURETTES CL. B 10:0,02 ML, STRAIGHT STOPCOCK is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Burettes, inside Volumetric glassware, 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.
