Description
Silicone tubing with an internal diameter of 12 mm, an external diameter of 18 mm and a wall thickness of 3 mm is a laboratory hose manufactured from silicone. The defined geometry gives a clear 12 mm bore, 18 mm outer diameter and 3 mm wall for consistent connection to matching fittings. Supplied in a pack size of 25 m, the tubing has a net weight of 0,168 kg. Material is silicone throughout, as stated for this product from manufacturer Deutsch & Neumann. Country of origin is Germany. The combination of 12 mm internal diameter, 18 mm external diameter and 3 mm wall thickness provides a uniform silicone tube profile suited to laboratory fluid lines that require these exact dimensions. The 25 m unit length supports multiple installations or continuous runs from a single pack. Net weight of 0,168 kg corresponds to the silicone volume of the stated cross-section. Dual-use classification is given as no. This silicone tubing therefore delivers the specified internal diameter, external diameter, wall thickness, pack length and material identity in one clear laboratory product format.
This article is part of Silicone tubing, in Tubing, hoses & fittings.

Questions about Silikon tubing Inner diameter: 12 mm Outer diameter: 18 mm Wall thickness: 3 mm
What is this article?
Silikon tubing Inner diameter: 12 mm Outer diameter: 18 mm Wall thickness: 3 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.
