Beschrijving
Blank stoppers, PFA, type 3 are sealing plugs for capillary connections with UNF 1/4'' 28G thread. Colourless and produced from chemically resistant PFA, they hermetically close unused ports on Safety Caps and prevent unwanted escape of liquids or vapours during solvent handling and laboratory fluid transfer. The inert polymer construction offers broad chemical compatibility for analytical and preparative workflows, including HPLC solvent reservoirs and chromatography systems. Supplied in a pack of 5 pieces from manufacturer SCAT, these blank stoppers are universally applicable and can be combined with Safety Cap products from other manufacturers as well. Matching versions for different thread sizes across the range allow flexible adaptation to existing laboratory setups. By blanking off idle connections, they help maintain closed, leak-tight fluid paths and support safe, clean operation in everyday laboratory environments where chemical resistance and reliable sealing are essential.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Blind Plug, PFA, Type 3
What is this article?
Blind Plug, PFA, Type 3 is the article on this page. Luminix Health distributes SCAT for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labmateriaal.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
