Beschrijving
Feed-through with silicone stopper is a laboratory accessory providing a sealed passage through an equipment wall. This 50 mm unit is intended for right-side mounting and uses a silicone stopper to close the opening securely around inserted lines or probes. Packaged as one piece, it has a net weight of 0,5 kg and a gross weight of 1 kg, making it straightforward to stock and install in the laboratory. The feed-through comes from manufacturer Binder and is produced in Germany, specifically in the Baden-Württemberg region. As lab material it supports controlled environments where cables, sensors or small tubing must enter a chamber or housing without leaving an open gap. The silicone stopper offers a practical, flexible seal suited to common laboratory pass-through needs. Right-side orientation distinguishes this variant for correct placement on the corresponding equipment side. Dimensions centre on the 50 mm feed-through diameter given in the manufacturer description, helping ensure fit with matching ports on compatible laboratory systems.
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 Labmateriaal.
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.
