Sapphire tubes are ideal material for wide range of industrial applications such as semi-conductors processing, test and analytics, and Lamps and Lamp Envelopes. Typical applications for test and analysics include Biological and chemical sample analysis, Nuclear Magnetic Resonance spectroscopy, Mass spectroscopy, plugged tubes, Thermo-optic temperature measurement, and Inline Petroleum processing analysis. Sapphire tubes are also used as Plasma containment tubes, Process gas injectors, Thermocouple protection, Water treatment, and High intensity lamps. Sapphire tube exhibits high mechanical strength. Sapphire tube with thick walls can be used to house sensors or lasers and protect sensors or lasers from extreme pressure. Its outer diameter and inner diameter can be polished to enable laser light emission and the reflected light measurement. Sapphire tube is ideal for the applications of high pressure systems and vacuum atmospheres. Sapphire tube is the preferred material for plasma containment due to its chemically inert and corrosion resistance. The chemical resistance enable sapphire tube to withstand extreme plasmas with no particle generation.
Our origin is Kenya but we also source from Tanzania. The minimum order is 20kgs. They can be rough or polished depending on the preference of the buyer. The price would also depend on the size and whether they are raw or polished and also the destination port.
