Description
Rotilabo®-Mini tubing reducers in polypropylene (PP) are straight hose connectors for laboratory liquid-handling lines that join tubing with an inner diameter from 1,6 mm to 4,0 mm. These compact reducers create a simple inline transition between flexible hoses of different bore sizes in research, analytical and routine laboratory workflows. Made from PP, they offer a lightweight option for everyday tubing assemblies within hose and accessory setups. The straight geometry keeps the fluid path direct, without introducing extra bends at the connection point. Each unit is supplied as a pack of 10 pc(s) with a total weight of 0,032 kg, which is practical for bench stocking and repeated use in liquid-handling stations. Part of the Rotilabo® range from manufacturer ROTH SELECTION, the mini reducers sit naturally among labware hose connectors used to organise sample transfer lines, reagent feeds and general fluid circuits. They are intended for tubing whose inner diameter falls within the stated 1,6–4,0 mm window, supporting stepwise diameter adaptation in small-scale laboratory hose systems where a neat, straight PP reducer is required.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.

Questions about Rotilabo®-Mini tubing reducers, PP, straight, f. tubing inner-Ø 1.6-4.0 mm
What is this article?
Rotilabo®-Mini tubing reducers, PP, straight, f. tubing inner-Ø 1.6-4.0 mm is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
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.
