The tube furnace CY-O1200-R100IT-AF is a rotary tube furnace with automatic feeding and collecting equipment. It adopts double-layer air-cooling structure, the surface temperature of the furnace body is ≤60℃, and it adopts high-purity alumina polycrystal. The furnace made of high purity alumina polycrystalline fiber, and the heating element is imported heating wire, which can prolong the service life of the furnace. The structure of the whole machine is reasonable, the shape is unique, the operation is simple and easy to learn. It is an ideal product for sintering, melting and analyzing metals, non-metals and their compounds under multiple atmospheres or vacuum conditions. The furnace tube of the device can be rotated at a speed of 0 to 10 rpm, and the furnace body can be inclined with respect to the plane at an angle of 0 to 10° to complete the collection process after the reaction.
