Description
Feed-through with silicone stopper is a laboratory accessory combining a 50 mm feed-through with an integrated silicone stopper for right-hand installation. It creates a defined passage through equipment walls so that cables, sensors or tubing can be routed while the silicone stopper supports sealing of the opening when continuous access is not required. The unit is supplied as 1 pc, with a net weight of 0,5 kg and a gross weight of 1 kg, which simplifies handling, storage and mounting on compatible instruments. This right-side 50 mm layout follows the geometry indicated for the variant and helps match chamber or cabinet orientation in the laboratory. From manufacturer Binder, the feed-through belongs to standard laboratory material ranges used with controlled-environment and general lab equipment. Country of origin is Germany, in the Baden-Württemberg region. Laboratories can select this right-hand 50 mm feed-through with silicone stopper wherever a dedicated access port and flexible sealing element are needed. The silicone stopper provides a resilient interface at the feed-through, suited to routine research and quality-control setups that depend on stable external connections without altering the basic chamber configuration.
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.
