Description
Rotilabo® reducing connectors are white polypropylene hose fittings with a stepped outlet of 4,6/1,6 mm for linking tubing of different internal diameters in laboratory liquid-handling systems. Supplied in packs of 10 pc(s), they support compact, organised stock for benches where diameter transitions are frequently required. The polypropylene construction is suited to routine laboratory tubing work involving aqueous media and many common lab fluids, while the reducing geometry enables a controlled step between larger and smaller hose ends. With a pack weight of 0,051 kg, the connectors are light to store alongside other hose accessories. They form part of the labware category for hoses and connectors used in sampling lines, transfer setups and general fluid routing. Offered from manufacturer ROTH SELECTION under the Rotilabo® range, the white finish helps distinguish fittings quickly during assembly or inventory checks. Clear outlet sizing (4,6/1,6 mm) simplifies matching to existing tubing, making these reducing connectors a practical choice whenever stepped polymer joints are needed in defined multi-piece packs.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.

Questions about Rotilabo®-reducing connectors, PP, white, outlet 4.6/1.6 mm, 10 unit(s)
What is this article?
Rotilabo®-reducing connectors, PP, white, outlet 4.6/1.6 mm, 10 unit(s) 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.
