Description
Feed-through with silicone stopper is a laboratory feed-through accessory in a 125 mm top-mounted design for sealed wall or chamber penetrations. It integrates a feed-through path with a silicone stopper so instrumentation lines can be introduced while retaining a practical stopper seal at the opening. The product belongs to laboratory material ranges used when a defined top entry and silicone stopper interface are needed for routine equipment setups. Pack size is 1 pc, with a net weight of 0,5 kg and a gross weight of 1 kg according to the stated specifications. Available from manufacturer Binder, the unit is of German origin (Baden-Württemberg) and is described for top placement at 125 mm. Typical use is in laboratory environments that require a top-position feed-through with silicone stopper for chambers, cabinets, or comparable enclosures. Confirm the 125 mm size, top mounting orientation, and stopper arrangement against the target apparatus so the accessory aligns with the intended penetration and sealing layout.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Access port with silicone plug
What is this article?
Access port with silicone plug is the article on this page. Luminix Health distributes Binder for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
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.
