The Thermo Scientific Thermolyne Atmosphere Controlled Ashing Furnaces are ideal for coal and coke ashing procedures.

• Programmable with one (1) stored program of eight (8) segments.
• Each segment includes one ramp and one dwell, so you can program 8 ramp/dwell cycles.
• The ramp is used to vary the heat-up rate to your specified setpoint. The furnace will then dwell (hold the temperature) at a set level for a specified time.
• An LED display simultaneously shows both setpoint and actual furnace temperatures.
• Reaches 975°C with the standard stainless-steel manifold and 1093°C with the optional inconel manifold (part number AY718X1)
• Adjustable gas flowmeter/valve (0-80L/min) on front for easy access when adjusting the airflow rate
• Stainless-steel manifold at rear chamber prewarms incoming gases and provides a maximum temperature gradient of only ±3°C at 750°C
• Chamber rear has a 0.95cm (0.38in.) diameter port for monitoring chamber temperatures with independent measuring devices
• Includes 0.64cm (0.25in.) I.D. or 0.96cm (0.375in.) O.D. hose barb (in back of chamber) for inert gas line
• Includes two dual-purpose stainless-steel trays and handle to accommodate 24 (30mL) porcelain crucibles or 38 (10mL) quartz crucibles
• Meets ASTM D3174 specifications: 3 to 4 air exchanges per min.
• Can be programmed to norm: Heating rate of 8°C/min. to 500°C, 6°C/min. from 500°C to 750°C, Hold at 750°C for two hours, then turn off automatically
