Description
Teflon cap for 8 390 101 is a dedicated closure accessory for the Swiegot-type vacuum filtration apparatus with a 60 ml funnel capacity. Made from Teflon, the cap is intended to match apparatus number 8 390 101 and provides a chemically resistant polymer cover for the filtration assembly during laboratory vacuum filtration work. It serves as a practical spare or replacement part when the original closure must be renewed, helping keep the filtration train protected between sample preparation and filtration steps. The single-piece unit has a net weight of 0,034 kg and a gross weight of 0,034 kg, so it remains light and easy to handle on the bench. Offered from manufacturer Witeg, this Teflon cap aligns with the specified funnel volume and apparatus designation used in many analytical and research laboratories. Typical use cases include routine vacuum filtration of solutions, sample clarification, and general laboratory filtration workflows where an inert polymer seal is preferred. Supplied as one piece per pack, it supports straightforward stock replenishment for quality-control, teaching, and research environments that operate Swiegot-style vacuum filtration devices with 60 ml funnels.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Teflon cap for 8 390 101
What is this article?
Teflon cap for 8 390 101 is the article on this page. Luminix Health distributes Witeg 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.
