Tubes with an outer diameter as small as 0.15mm are available in lengths ranging from a fraction of a metre to large production runs. The 0.15mm OD tube is 99.95% gold and has an inner diameter of 0.05mm.
In addition to gold, there are 37 pure metal, alloy, and polymer ultra-thin tubes (OD ≤0.5mm) available from Goodfellow stock, as well as a wide range of tubes in larger diameters and in other materials. Custom fabrication is also often available upon request.
Applications for ultra-thin tubes are many, and often relate to the need for greater miniaturization, lighter weight or flow restriction. Goodfellow
