    Specific Introduction:
        KJ-OTF-1200-80 is an idea system for graphene growth, it consists of one split tube furnace with 80mm diameter and 300mm long hot zone, one quartz tube or alumina tube is available. Its tube chamber could reach a high vacuum degree of 6.7*10-3Pa under cold state, it is also good choice for vacuum sintering. The gas-rout is specialy designed for N2 gas, H2 gas and CH4 gas. User can also choose other gases according to actual processing technology.
