Description
Feed-through with silicone stopper is a laboratory accessory for sealed passage through equipment housings or chamber walls. Specified at 30 mm and intended for top mounting, it combines a defined feed-through opening with a silicone stopper that supports cable, tubing or sensor routing while helping preserve the integrity of the internal working space. The silicone stopper offers a flexible, resilient seal suited to routine laboratory access needs on incubators, climate chambers and related controlled-environment systems. Installed in the upper position, the feed-through enables practical connection of probes or lines without unnecessary disturbance of temperature or atmosphere conditions inside the unit. Supplied as one piece with a net weight of 0,5 kg and a gross weight of 1 kg, it is ready for integration into compatible laboratory equipment. This accessory from manufacturer Binder belongs to the laboratory materials category and supports everyday workflows in research, quality control and production laboratories where reliable top-mounted sealing and access are required. The 30 mm dimension addresses common port sizes used on chamber systems, making the feed-through a clear fit for standard laboratory configurations that demand both accessibility and environmental control.
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 Matériel de laboratoire.
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.
