Our small high temperature laboratory furnace is capable of running at 3000 °C in inert gas with modest power usage due to the highly efficient graphite insulation pack. The 4″ diameter x 8″ high (101 mm x 204 mm) hot zone is suited for small batch processing or material research at ultra high temperatures. Operation in vacuum is also possible but is limited to 2200°C to maximize lifetime of the heating element and shields. Operation through the (optional) HMI interface is intuitive and easy-to-learn. A retracting temperature thermocouple is used for low temperature control. The RTC will retract automatically and switch over control to a pyrometer at a pre-set temperature setpoint. Applications include: sintering, carbon fiber processing, carbonizing, ceramic firing, degassing, heat treating and more. Specifications Top loading with hinged cover. Graphite zone (tungsten hot zone available). +/- 10 °C temperature uniformity. 4″ diameter x 8″ high (101 mm x 203 mm) hot zone. HMI control system with Data-acquisition. TC and Pyrometer temperature control. Details 1. Chamber and Hot Zone The furnace chamber is round and is supplied with a hinged top lid to facilitate loading and unloading. The chamber is double-walled, manufactured from 304L grade stainless steel and is welded together by the heli-arc method. The chamber is electro-polished for a clean, shiny and durable finish. In our graphite type hot zones, we utilize fibrous graphite insulation. A resistance-heated graphite element surrounds the work area. Power to this element is delivered through a set of graphite pins that require no threaded connections. This reduces down time for element replacement.
