Description
Rotilabo® silicone tube with an inner diameter of 20 mm and an outer diameter of 26 mm is laboratory hose for general liquid-handling use. Offered in a 5 m length, the product supplies enough material to cut individual runs for transfer lines, instrument connections and other routine laboratory fluid paths. Defined inner and outer diameters support reliable matching to fittings and accessories intended for this larger bore. With a pack weight of 1,300 kg, the coil is still practical to store and handle when preparing working lengths. This Rotilabo® silicone tube from manufacturer ROTH SELECTION belongs to the hoses and accessories range for general applications in labware and liquid handling. It suits setups that specify silicone tubing at 20 mm inner Ø and 26 mm outer Ø for everyday routing duties. Multiple shorter segments can be taken from the single 5 m unit, helping laboratories maintain consistent tubing dimensions across related equipment. Clear geometry together with the stated pack length make this a convenient choice for general-purpose silicone hose inventory.

Questions about Rotilabo®-silicone tube, inner-Ø 20 mm, outer-Ø 26 mm, 5 m
What is this article?
Rotilabo®-silicone tube, inner-Ø 20 mm, outer-Ø 26 mm, 5 m is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Silicone tubing, inside Tubing, hoses & fittings, in Matériel de laboratoire.
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.
