Description
Feed-through with inner diameter 23 mm, sealable, standard placement is a laboratory chamber accessory for routing cables, sensors or tubing through the housing wall while keeping the opening closable when not required. The 23 mm inner diameter provides a defined passage suited to common laboratory connections, and the sealable design supports controlled use during thermal or climatic processes. Standard placement is right centre/centre, aligning with typical chamber layouts so installations remain consistent across comparable units. Offered as 1 pc, this feed-through is intended for professional laboratory material setups in ovens, incubators and related climate chambers where external lines must enter the working space in an orderly way. The component comes from manufacturer Memmert and reflects established German laboratory equipment practice for chamber accessories. When sealed, the opening helps limit unnecessary exchange with the surroundings; when open, it enables probe or cable feed-through for monitoring and control tasks. Laboratories specifying a fixed right-side centre position can integrate this option into standardised equipment configurations for research, quality control and routine laboratory work without redesigning the chamber interface.

What is this article?
Entry port with 23 mm clear diameter, can be closed, standard position; right ce 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.
