Description
Rotilabo® reducing connectors provide dependable polypropylene fittings for laboratory hose systems that require a controlled change in tubing diameter. Produced in white PP, they feature an outlet of 7,5/4,6 mm, bridging larger and smaller flexible lines used in liquid handling, sampling, and general fluid routing. The reducing profile supports secure hose engagement and helps preserve flow continuity when linking instruments, reservoirs, or temporary transfer circuits on the bench. Polypropylene construction offers the chemical resistance expected for many aqueous media and mild laboratory solvents. Supplied in packs of 10 pc(s) with a pack weight of 0,082 kg, the connectors are convenient for equipping multiple stations or replenishing shared accessory drawers. These Rotilabo® components from manufacturer ROTH SELECTION fit naturally into hose-connector and liquid-handling setups across research and routine laboratory environments. Use them wherever a clean 7,5 to 4,6 mm step is needed without bulky multi-piece adapters, keeping tubing assemblies compact, repeatable, and simple to reconfigure between protocols.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.

Questions about Rotilabo®-reducing connectors, PP, white, outlet 7.5/4.6 mm, 10 unit(s)
What is this article?
Rotilabo®-reducing connectors, PP, white, outlet 7.5/4.6 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.
