Our quartz tubes are often used as base material for a multitude of processed products. It is possible to decrease the hydroxyl content down to 2ppm, which is usually needed for the production in lighting applications (such as medium pressure emitters). Our broad stock range of our standard material EN09 tubes includes tubes from Ø4mm to Ø100 mm with a standard length of 1500mm. But of course they can be cut to shorter lengths by our glass treatment if this is needed for your application. Please do not hesitate to contact us if the diameter you need is not on the list, since we can also produce other dimensions on request.
