Warning	Do NOT use an alumina tube under a vacuum at a temperature > 1500°C. Max heating or cooling rate < 5°C/ minute. Please keep the thermal gradient less than 100°C/ inch to avoid cracking. Please separate parts from the inside surface of the tube to avoid thermal shock. Please handle the tube carefully. No warranty for the tube.
Application Notes	Replace tube for MTI multi-zone tube furnaces of SWGL-1700Z2 Dual Zone, SWGL-1600Z2 Dual Zone, and SWGL-1600Y Three Zone Please click here to learn how to use and maintain an Alumina tube in an MT temperature tube furnace. In order to get longer tube service life, Please use quartz or alumina crucible to carry the sample, instead of loading the sample directly inside the tube, please click the picture below to choose one crucible boat:
