Description
Burette class B SB 25:0,05 ml with straight valve stopcock and PTFE spindle is precision volumetric glassware manufactured from DURAN® borosilicate glass 3.3. Blue graduated with Schellbach stripe and clear line division, it delivers a nominal volume of 25 ml at a scale division of 0,05 ml in accordance with DIN EN ISO 385. The straight valve stopcock fitted with a PTFE spindle ensures smooth, chemically resistant control of liquid delivery during titration. Supplied in packs of 2 pieces, these instruments from manufacturer Hirschmann suit general laboratory titration, educational settings and routine analytical work requiring class B accuracy. The Schellbach stripe improves meniscus visibility while the blue graduation provides clear contrast against aqueous media. Construction from borosilicate glass 3.3 offers the thermal-shock and chemical resistance expected of quality laboratory glassware. Suitable for quality-control laboratories, teaching environments and research titrations that demand dependable volume measurement and easy handling in everyday use.

Questions about BURETTES CL. B SB 25:0,05 ML, STR.VALVE STOPC., PTFE SPINDLE
What is this article?
BURETTES CL. B SB 25:0,05 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 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.
