Description
Silicone feed-through 30 mm rear (CB) is a laboratory chamber accessory designed as a sealed access port with an integrated silicone stopper. The 30 mm opening supports controlled routing of sensors, cables, or tubing into climate and environmental chambers while helping maintain the integrity of the working atmosphere. Oriented for rear-side installation, this configuration suits setups where rear wall access is preferred for instrumentation or process connections. Supplied as a single piece with a net weight of 0,5 kg and a gross weight of 1 kg, the unit is straightforward to stock and fit during chamber configuration or retrofit work. Manufactured by Binder, the feed-through with silicone stopper is intended for routine laboratory material use in controlled-environment equipment. Typical applications include temperature and humidity chambers, stability testing systems, and other CB-series related installations that require a defined rear feed-through path. The silicone stopper provides a practical sealing interface around inserted lines, supporting flexible experimental layouts without unnecessary hardware complexity. Originating from Germany (Baden-Württemberg), this accessory complements standard lab chamber workflows where reliable rear access and simple stopper-based sealing are required.

Questions about Access port silicone plugs 30 mm, back
What is this article?
Access port silicone plugs 30 mm, back is the article on this page. Luminix Health distributes Binder for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Matériel de laboratoire.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
