Burette class B SB 25:0,05 ml with lateral valve stopcock and PTFE spindle is a precision volumetric glassware item made from DURAN® borosilicate glass 3.3. It carries blue graduation markings together with a Schellbach stripe that improves meniscus readability during titration. The nominal volume is 25 ml and the scale division is 0,05 ml, delivering class B accuracy in accordance with DIN EN ISO 385. A lateral valve stopcock fitted with a PTFE spindle provides smooth, chemically resistant control of liquid flow. This Schellbach-type rapid-operation burette is well suited to routine quantitative analysis, quality-control titrations and teaching laboratories. The borosilicate 3.3 construction offers good thermal shock resistance and broad chemical compatibility with aqueous and many organic reagents. Pack size is 2 pieces; the instrument is supplied by manufacturer Hirschmann and is intended for everyday analytical work where reliable class B performance is required. Clear line graduation and the lateral PTFE valve design support efficient, reproducible dispensing in busy laboratory environments.

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