Description
Feed-through with silicone stopper is a laboratory accessory for creating a sealed passage through chamber walls while accommodating cables, sensors, or similar lines. This 50 mm left-side variant is intended for climate, temperature, and other controlled chambers used in research and quality-control laboratories. An integrated silicone stopper supplies a flexible sealing interface that helps keep the working atmosphere stable during connection and routine use. The product is supplied as one piece, with a net weight of 0,5 kg and a gross weight of 1 kg, making it convenient to hold as laboratory material for service or upgrade work. From manufacturer Binder, the feed-through suits compatible chamber designs that specify a left-hand 50 mm silicone-stoppered port. Defined diameter and mounting side reduce selection errors against equipment documentation. Laboratories can deploy it as a replacement or additional access point so instrument routing remains practical without compromising chamber integrity in controlled-environment applications.
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.
