OTF1200X-S is a CE certified compact and energy saving (1200W power consumption) split tube furnace with a max. working temperature of 1200°C. The furnace can be adopt either a 1" or 2" O.D quartz tube (optional) with a pair of stainless steel vacuum sealing flanges. The 1/4" barb fitting for rubber hose connection allows heating sample in vacuum or flowing gas. Built-in precision temperature controller can provide up to 30 segments of heating and cooling steps with +/- 1 °C accuracy.
