Description
Laboratory tubing (NR), red, with an inner diameter of 4 mm and an outer diameter of 6 mm is a flexible natural rubber hose for general laboratory fluid handling and apparatus connection. The tubing features a wall thickness of 1 mm and is supplied as a continuous 25 m length, allowing sections to be cut to the required size for individual setups. Made from rubber (NR) in a distinctive red colour, it supports clear visual identification of lines in busy laboratory environments. This product from manufacturer Deutsch & Neumann has a net weight of 0,01766 kg and offers the elasticity typical of natural rubber for straightforward installation on standard fittings and glassware. The precise 4 mm inner diameter and 6 mm outer diameter ensure consistent fit with common laboratory connectors. Suitable for everyday research, teaching and routine analytical work, the tubing provides a practical, flexible solution for transferring liquids or gases in non-critical applications. Its uniform wall and smooth bore facilitate reliable flow while remaining easy to handle and store. The red NR laboratory tubing is a standard consumable for organising multiple fluid paths on the bench.

Questions about laboratory tubing (NR), red Inner diameter: 4 mm Outer diameter: 6 mm Wall
What is this article?
laboratory tubing (NR), red Inner diameter: 4 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.
