Croft Filters are one of very few Dixon Ring suppliers. Invented by Olaf George Dixon in 1946, Dixon Rings are made of stainless steel mesh material. They come in various sizes: some as small as 1/16".
Historically, the sheer cost of manufacturing these tiny components in any great quantity was a major obstacle. Today, this is no longer the case.
At Croft Filters, we have developed a machine that automates the entire process of making Dixon Rings at high speed. As a result, we can produce Dixon Rings in very high volumes - something we could never have achieved without our employees’ outstanding design skills and manufacturing excellence.
Random Column Packing
Available in diameters of 1/16", 1/8" and 1/4", Dixon Rings can be packed in their millions into distillation columns, producing a remarkably large surface area in a small volume. See: Dixon Rings – Filtration Journal
