Description
Laboratory tubing (NR), red, inner diameter 3 mm, outer diameter 6 mm is a flexible natural-rubber hose intended for laboratory fluid handling and apparatus connections. It offers an inner diameter of 3 mm, an outer diameter of 6 mm and a wall thickness of 1,5 mm, providing increased wall strength compared with thinner variants while retaining flexibility. Produced from natural rubber (NR) in red colour, the tubing enables rapid visual differentiation of circuits within multi-line installations. Available from manufacturer Deutsch & Neumann in a 25 m pack, it can be cut to the exact lengths needed for glassware links, temporary transfer lines or wash-bottle assemblies. Net weight is 0,0274 kg. The elastic rubber material withstands repeated bending and supports reliable sealing on standard barbed or glass connectors used in analytical and teaching laboratories. Red colour coding assists operators in avoiding cross-connections when several media streams run in parallel. The smooth internal surface promotes steady flow and simplifies rinsing between experiments. This tubing suits aqueous solutions and mild laboratory reagents under typical low-pressure conditions encountered in research and quality-control environments.

Questions about laboratory tubing (NR), red Inner diameter: 3 mm Outer diameter: 6 mm Wall
What is this article?
laboratory tubing (NR), red Inner diameter: 3 mm Outer diameter: 6 mm Wall is the article on this page. Luminix Health distributes Deutsch & Neumann for laboratory use. It sits in PVC, PTFE & other tubing, inside Tubing, hoses & fittings, in Labware.
PVC is the flexible everyday tube for water and mild aqueous liquids. PTFE is the stiff, almost inert tube for solvents. Other polymers sit between them. The bore, the wall and the chemical resistance are the specification, and the tube is cut to length.
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.
