Description
Replacement screw cap, PFA, for bottles with thread S 40 is a high-performance closure designed for wide-neck laboratory bottles. Made from chemically inert perfluoroalkoxy alkane (PFA), the cap withstands a wide range of solvents, acids and bases while retaining dimensional stability under typical laboratory temperature conditions. The S 40 thread provides a secure, leak-resistant seal that is simple to open and close, supporting safe storage and handling of reagents or samples. Offered as a single replacement unit from manufacturer Brand, this screw cap is intended for Weithals bottles and other vessels equipped with the matching S 40 finish. Its robust fluoropolymer construction minimises extractables and supports repeated cleaning or sterilisation procedures. Suitable for analytical chemistry, sample preparation and general laboratory storage applications, the PFA screw cap delivers reliable long-term performance where chemical resistance and clean sealing surfaces are required.

Questions about Replacement screw cap, PFA, for bottles, thread S 40
What is this article?
Replacement screw cap, PFA, for bottles, thread S 40 is the article on this page. Luminix Health distributes Brand for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
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.
