0.0/5 rating (0 votes)


Item Number: SL-1500X-OTF-80SL

GSL-1500X-OTF-80SL is a CE certified slide-able tube furnace with 80mm ODx55"L mullite tube, vacuum flanges and a max. working temperature of 1500°C. One pair of sliding rail is installed on the bottom of furnace. The furnace can be moved manually from one side to the other for achieving a max. heating or cooling rate up to 100°C/min. For fastest heating, the furnace may be pre-heated to a desired temperature and then be slided to the sample's position. As for fastest cooling, the furnace can be slided to another side after sample heating is completed. Moreover, the heating and cooling rates may reach 50°C/s under vacuum or inert gases. This furnace provides an alternative for rapid thermal processing at the lowest cost.
