Description
Feed-through with inner diameter 23 mm, sealable, standard placement; left centre/centre is a laboratory accessory port for routing cables, sensors, probes or tubing into a controlled chamber. The 23 mm inner diameter accommodates common laboratory connections, while the sealable design allows the opening to be closed when not required, supporting chamber integrity during temperature-controlled or environmentally sensitive work. Standard placement on the left at the centre/centre position provides a defined installation location on compatible equipment, simplifying planning of external instrumentation and media lines. Delivered as 1 pc, this feed-through is intended for laboratory material applications in research, development and quality-control settings. The accessory comes from manufacturer Memmert and is classified with dual-use indicator no. Country of origin is Germany (Bavaria). By combining a practical inner diameter with a closable interface and fixed standard positioning, the component supports flexible process monitoring and connection setups without permanent open ports on the chamber wall.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.

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