Description
Feed-through (silicone) with an inner diameter of 40 mm is a moisture-tight access port that can be closed with a silicone stopper. Designed for climate chambers and similar laboratory equipment, it allows cables, sensors or tubing to pass through the rear wall while limiting moisture ingress into the working space. The silicone construction supports a tight seal under humid operating conditions, and the port can be placed individually in the rear wall; the desired position should be specified when ordering. According to the product data, this accessory is not intended for ICH L models. From manufacturer Memmert, the unit serves laboratories that need flexible feed-through positioning together with reliable moisture protection. Supplied as one piece, it supports stability testing, climatic simulation and related controlled-environment applications where external connections must not undermine humidity setpoints. The 40 mm inner diameter provides ample clearance for thicker leads or multiple lines, and the closable silicone stopper helps restore chamber integrity when the penetration is not in active use. Ideal where humidity control is critical and fixed standard side placements are insufficient.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Entry port (silicone), 40 mm clear diameter, moisture tight, can be closed by si
What is this article?
Entry port (silicone), 40 mm clear diameter, moisture tight, can be closed by si is the article on this page. Luminix Health distributes Memmert 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.
