Description
Seal, FKM, for burette stopcock 11805 is a replacement sealing element made from FKM elastomer, designed specifically for use with burette stopcock 11805 as well as compact burettes and titration apparatus. The FKM material offers good chemical resistance for typical laboratory titration media and ensures a reliable seal at the stopcock interface during volumetric work. This single-piece accessory supports maintenance of existing Brand glassware setups, restoring proper function without replacing the entire stopcock assembly. Compact dimensions and low net weight of approximately 0,011 kg make it easy to stock as a spare part. Ideal for analytical laboratories performing precise titrations where leak-free operation of the burette stopcock is essential. The seal is supplied non-sterile as a standard laboratory consumable component.

Questions about Spare sealing f.stopcock 11805
What is this article?
Spare sealing f.stopcock 11805 is the article on this page. Luminix Health distributes Brand for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labware.
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.
