Description
Silicone tubing with an internal diameter of 16 mm, external diameter of 21 mm and wall thickness of 2,5 mm is a flexible laboratory hose designed for fluid transfer and general laboratory applications. Manufactured from silicone, it offers the dimensional stability needed for reliable connections in research and process environments. The tubing is supplied in a convenient 20 m length and has a net weight of 0,181 kg, making it practical for bench-top or system installations. Its smooth bore and consistent wall support clean flow characteristics while remaining easy to cut and fit to standard laboratory fittings. This silicone tubing from manufacturer Deutsch & Neumann is suitable for a wide range of non-critical transfer tasks where chemical resistance and flexibility of silicone are advantageous. The product originates from Germany and belongs to the silicone hose category commonly used alongside other polymer tubing options in laboratory setups. Clear dimensional markings allow straightforward selection and replacement in existing assemblies.

Questions about Silikon tubing Inner diameter: 16 mm Outer diameter: 21 mm Wall thickness: 2,5
What is this article?
Silikon tubing Inner diameter: 16 mm Outer diameter: 21 mm Wall thickness: 2,5 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.
