Description
Replacement plug for Pellet titration apparatus is a PTFE stopcock insert designed for the intermediate stopcock with safety lock on brown-glass Pellet burette systems. The plug is specified as PTFE 4 NS/14, matching the joint geometry used on classic Pellet titration setups so worn or damaged Küken components can be renewed without replacing the entire apparatus. PTFE construction provides chemical resistance to common titrants and aqueous reagents while the integrated safety lock helps keep the plug seated during operation and storage. Intended for volumetric and analytical laboratories that maintain Pellet-type titration equipment, this spare part restores reliable flow control at the intermediate stopcock. Supplied as a single piece from manufacturer Brand, it supports routine maintenance of glass titration lines where precise stopcock function is essential. Compatible only with the corresponding intermediate stopcock configuration on Pellet apparatus; verify joint size NS/14 before installation.
This article is part of Burettes, in Volumetric glassware.

Questions about Spare key for Pellet automatic burette, PTFE, for intermediate stopcock
What is this article?
Spare key for Pellet automatic burette, PTFE, for intermediate stopcock 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.
