Description
Rotilabo® silicone tube with an inner diameter of 4 mm and an outer diameter of 7 mm is a flexible laboratory hose intended for general liquid-handling applications. Supplied as a 25 m continuous length, it supports fluid transfer, instrument connections and distribution work across routine laboratory workflows. The silicone material delivers the flexibility needed for bench routing and repeated handling with media for which silicone is appropriate. At 0,775 kg for the full pack, the coil remains manageable for storage and installation. The 4 mm internal bore combined with a 7 mm outer diameter provides a slightly thicker wall than narrower variants, aiding mechanical robustness while retaining a compact flow path. This Rotilabo® hose from manufacturer ROTH SELECTION belongs to the category of hoses for general laboratory applications and pairs with standard fittings used in liquid-handling setups. Laboratories employ such tubing for supply and waste lines, temporary fluid bridges and instrument interfaces where pliability simplifies layout. The 25 m unit quantity covers multiple workstations from a single coil and limits restocking interruptions. Select this dimension when a 4 mm bore with a reinforced outer profile is preferred for everyday research, QC or teaching duties.

Questions about Rotilabo®-silicone tube, inner-Ø 4 mm, outer-Ø 7 mm, 25 m
What is this article?
Rotilabo®-silicone tube, inner-Ø 4 mm, outer-Ø 7 mm, 25 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 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.
