Description
Silicone tubing with an internal diameter of 1,5 mm, an external diameter of 3 mm and a wall thickness of 0,75 mm is a fine-bore laboratory hose suited to low-volume fluid lines and compact instrument connections. The silicone material provides a flexible tube with a narrow 1,5 mm internal channel and a slim 3 mm outer profile, while the 0,75 mm wall keeps the cross-section light and easy to route. Pack size is 25 m, so longer continuous lengths or multiple cut pieces can be prepared from a single supply. Net weight is 0,00667 kg. Offered by manufacturer Deutsch & Neumann and originating from Germany, this silicone tubing addresses applications that need small metric dimensions for sampling lines, micro-scale transfer or tight installation spaces. The clearly specified inner diameter, outer diameter and wall thickness support accurate matching to miniature fittings and ports. With its defined silicone construction and compact geometry, the tubing is a practical choice wherever a 1,5 mm bore and 3 mm outer diameter are required in laboratory or technical fluid handling.
This article is part of Silicone tubing, in Tubing, hoses & fittings.

Questions about Silikon tubing Inner diameter: 1,5 mm Outer diameter: 3 mm Wall thickness: 0,75
What is this article?
Silikon tubing Inner diameter: 1,5 mm Outer diameter: 3 mm Wall thickness: 0,75 is the article on this page. Luminix Health distributes Deutsch & Neumann for laboratory use. It sits in Silicone tubing, inside Tubing, hoses & fittings, in Labware.
Silicone tubing stays flexible across a wide temperature range and survives repeated autoclaving, which is why peristaltic pumps and media lines use it. It is not the choice for strong solvents, which migrate into the wall.
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.
