Description
Silicone tubing with internal diameter 3 mm, external diameter 5 mm and wall thickness 1 mm is a flexible laboratory hose intended for fluid and gas transfer applications. Manufactured from silicone, the tubing offers the dimensional accuracy required for reliable connections in analytical, biotechnological and general laboratory set-ups. The 3 mm internal bore combined with a 1 mm wall yields an external diameter of 5 mm, providing a balance of flow capacity and mechanical stability. Net weight is 0,0165 kg per unit length. This silicone tubing from manufacturer Deutsch & Neumann is supplied in a convenient 25 m length, making it suitable for installation in peristaltic systems, media lines or temporary transfer circuits. Originating from Germany, the product meets everyday laboratory demands for chemically resistant, flexible tubing that can be cut to the required length and fitted with standard connectors. Ideal for research, quality-control and process laboratories needing dependable silicone hose of these precise dimensions.

Questions about Silikon tubing Inner diameter: 3 mm Outer diameter: 5 mm Wall thickness: 1 mm
What is this article?
Silikon tubing Inner diameter: 3 mm Outer diameter: 5 mm Wall thickness: 1 mm is the article on this page. Luminix Health distributes Deutsch & Neumann for laboratory use. It sits in Silicone tubing, inside Tubing, hoses & fittings, in Labware.
Silicone tubing stays flexible across a wide temperature range and survives repeated autoclaving, which is why peristaltic pumps and media lines use it. It is not the choice for strong solvents, which migrate into the wall.
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.
