Beschrijving
Feed-through with silicone stopper is a laboratory accessory consisting of a passage fitting with an integrated silicone stopper, specified as 50 mm for right-side installation. It provides a defined opening for routing through equipment walls while the silicone stopper supports a practical seal around lines, sensors or similar laboratory connections. Supplied as 1 pc, the unit has a net weight of 0,5 kg and a gross weight of 1 kg. This feed-through from manufacturer Binder originates from Germany (Baden-Württemberg) and belongs to laboratory materials used when configuring or maintaining chamber and housing access points. The 50 mm dimension and right-hand orientation help ensure correct selection for the intended mounting side and passage size. Laboratories employ such accessories where controlled access through a wall is required without unnecessary complexity. Clear size and side data support straightforward matching to compatible equipment layouts. The silicone stopper construction suits routine laboratory handling and installation tasks around controlled working spaces.

Questions about Access port
What is this article?
Access port is the article on this page. Luminix Health distributes Binder 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.
