Description
Feed-through with inner diameter 23 mm is a sealable access port for laboratory chambers, offering an individually selectable mounting position. The 23 mm inner diameter provides a defined passage for sensors, cables or tubing through the equipment wall and can be closed when the opening is not in use. The desired position must be stated when ordering; this version is intended for rear mounting. Supplied as one piece from manufacturer Memmert, the feed-through enables customised routing of measurement and media lines into incubators, climate chambers and comparable laboratory systems. Individual placement supports alignment with internal racks, sample positions or external instruments without relying on fixed factory openings. As laboratory material it serves controlled wall penetration while remaining closable between experiments. The component is designed for practical integration into existing chamber layouts rather than permanent structural alteration. Produced in Germany, it is delivered ready for installation after the rear position has been confirmed. This accessory suits laboratories that need flexible, sealable feed-through capability for routine thermal or climatic work.

What is this article?
Entry port with 23 mm clear diameter, can be closed, individual position (please is the article on this page. Luminix Health distributes Memmert for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
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.
