Combines microprocessor based programmability with a special furnace design that makes it ideal for coal and coke ashing procedures meeting ASTM D3174 specifications. The coal ashing furnace incorporates a three mode controller consisting of a 2-ramp programmable control which allows programming the rate of temperature increase and decrease (ramp), and length of time the temperature holds at specific levels (dwell).

Features

• Model F6000-60 meets ASTM D3174 specifications: 3-4 air exchanges per minute. Heating rate of 8C/min. 500C, 6C/min. from 500C to 750C. Holds at 750C for two hours, then turns off.
• Temperature range is 100C to 975C (212F to 1787F).
• Adjustable gas flow meter/valve (0-80 l/min.) conveniently located on front allows easy adjustment of airflow rate.
• Stainless steel manifold at rear chamber pre-warms incoming gases; provides maximum temperature gradient of only 3C at 750C.
• The rear of the chamber incorporates a 0.38" (0.95 cm) diameter port for monitoring chamber temperatures with independent measuring devices and a 0.25" ID or 0.375" OD hose barb on back of unit to connect with an inert gas line.
• Temperature to 975C with standard stainless steel manifold or Temperature to 1093C with optional inconel manifold.
• Manufactured in 0.5 and 1.6 cu. ft. capacities
• An enlarged vent hole on top of the furnace accepts 2" diameter flexible tubing for air exhaust.
• Chamber dimensions: 12-3/4" W x 6-3/4" H x 10" D. Overall dimensions: 19-1/8" W x 21" H x 20" D.

Supplied with

• All type F6000 units include two dual-purpose stainless steel trays and handle to accommodate 24 (30 ml) porcelain crucibles, or 38 (10 ml) quartz crucibles.
• No power cord supplied. Electrical connection requires fixed wiring.
