Description
Luer hose connectors in brass with an inner diameter of 3,0 mm and LLF configuration provide a larger-bore metal interface for laboratory hose and liquid-handling systems. The 3,0 mm inner opening supports higher volumetric throughput than narrower variants when coupling flexible tubing to Luer-compatible ports, syringes or manifolds. Brass delivers mechanical strength for repeated connect and disconnect cycles on the bench or at instrument inlets. Each unit is packed as 1 pc and has a weight of 0,003 kg, so it is easy to stock and assign to specific set-ups. The LLF side engages matching male Luer lock fittings for tool-free assembly. Offered by manufacturer ROTH SELECTION within the hoses-and-accessories labware line, this connector is aimed at controlled laboratory fluid paths in analytical, preparative or general liquid-transfer work. Its compact brass body and defined bore help maintain a stable geometry along short hose runs. Use it wherever a brass LLF Luer hose connector with 3,0 mm inner diameter is required for reliable coupling of laboratory tubing.

Questions about Luer hose connectors, Brass, inner Ø 3.0 mm, LLF, 1 unit(s)
What is this article?
Luer hose connectors, Brass, inner Ø 3.0 mm, LLF, 1 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.
