Description
Replacement plug for Pellet titration apparatus is a PTFE spare cock plug (Küken) intended for the intermediate stopcock with safety lock on clear-glass Pellet titration setups. Specified as PTFE 4 NS/19 with securing feature, it restores a reliable seal and smooth operation at the intermediate stopcock where wear or chemical attack has compromised the original plug. The inert PTFE material is well suited to aqueous and many organic titration media commonly used with Pellet apparatus, supporting clean shut-off and controlled reagent flow during volumetric work. This Brand replacement part is supplied as one piece and matches the geometry required for the secured intermediate stopcock on the clear-glass Pellet titrator. Pack dimensions and low net weight reflect a compact laboratory spare that is easy to stock for maintenance. Using a correctly sized NS/19 PTFE plug with safety lock helps keep the titration train leak-tight and mechanically secure during repeated open–close cycles. Ideal for laboratories that maintain classic Pellet titration glassware and need a direct PTFE spare for the intermediate stopcock assembly.
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.
