Specific Introduction:
KJ-1400X-Z8 is an open tube furnace with 8 temperature zones, equipped with mullite furnace tubes and stainless steel sealing flanges, and the maximum working temperature of the furnace body can reach 1400℃. The heating element is a SiC rod, and each temperature zone is controlled by an independent temperature control system, which can form a variety of temperature gradients in the furnace tube to meet various experimental requirements. Such as gradual functional materials, high-throughput methods to study phase change and recrystallization.

Application Notes	The tube furnaces with mullite tube are designed for using under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI Never use graphite crucible in alumina tube. Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min ) Vacuum limit definition for all mullite tube furnaces: * Vacuum pressures may only be safely used up to 1300°C
Warranty	One year limited warranty with lifetime support (consumable parts such as processing tubes, and O-rings are not covered by the warranty, please order replacements at related products below.). ATTENTION: Any damages caused by the use of corrosive and acidic gases are not under the coverage of Kejia One Year Limited Warranty.
