Side burette stopcock with glass key in clear glass is a laboratory accessory sized for 25 ml burettes. Fabricated from borosilicate glass 3.3 under the DURAN® registered trademark, it provides a side-mounted control element with a traditional glass key for volumetric titration and precise liquid delivery. Clear glass construction allows direct observation of the bore and key seating during everyday analytical use. Supplied as one piece, the stopcock is suited as a replacement or spare part for matching 25 ml burette assemblies in research, quality control and educational laboratories. The glass-key format aligns with classical ground-glass sealing practice used on DURAN® volumetric glassware. From manufacturer Hirschmann, this accessory sits in the burette accessories category and is specified for clear-glass side stopcocks on 25 ml burettes. Net weight is 0,047 kg, with packaging dimensions of 0,23 m depth, 0,11 m width and 0,095 m height. Apply standard laboratory glassware handling and cleaning methods for stopcocks to preserve smooth key movement and sealing performance in routine volumetric work.

Questions about BURETTE STOPC. LATERAL 25 ML, GLASS KEY, CLEAR GLASS
What is this article?
BURETTE STOPC. LATERAL 25 ML, GLASS KEY, CLEAR GLASS 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.
