Benchtop Muffle Furnace With Adjustable Shelf (48000 Model Only) From Thermo Scientific

• Features a heating range from 100°C to 1200°C (212°F to 2192°F)
• Chamber offers 120 or 350 cubic inches of heating space
• Ceramic shelf doubles work area; ideal for heating small parts (model 48000 only)
• Choose between electronic single set point control and programmable control
• .375" port allows injection of special atmospheres or monitoring of chamber temperature with independent measuring device

These muffle furnaces use open coil heating elements on both sides of the heating chamber to allow fast heating with minimal temperature gradient. This energy efficiency is enhanced through the use of high thermal-efficient ceramic insulation surrounding the chamber. The free-floating, ceramic fiber door includes a chamber plug that prevents heat loss around the door by totally sealing when the spring-loaded door is closed.

Electronic single setpoint controls enable you to heat up the muffle furnace to one single setpoint level and hold that setpoint temperature. A programmable control enables you to program up to eight ramps and eight dwell times. Thus you can choose among two chamber sizes and two temperature controllers. The digital single setpoint control features a single ramp to setpoint and a dwell, again with a single display but also with a mechanical Over Temperature Protection relay. The digital programmable control features 4 stored programs with 16 segments per program, along with RS232 communications. This microprocessor control features adjustable over-temperature protection, sensor-break protection, and digital readout of both setpoint and muffle furnace temperature.

A built-in venting system allows easy removal of undesirable contamination and moisture, making this muffle furnace especially suitable for use with sensitive microelectronic components. In addition, a .375" port allows you to purge the chamber with nitrogen or other special atmospheres, thereby enhancing moisture and contamination control; this port can also be used for independent temperature monitoring.

The interior chamber of Model 48000 (only) features built-in racks that allow adjustable positioning of a ceramic shelf (included), which effectively doubles the working area. Comes complete with on/off switch, thermocouple and grounded three-wire cord and plug.

Applications

• Gravimetric analysis
• Sintering
• Quantitative analysis
• Heat treating

Safety

• Door safety switch protects operator by removing power to the heating elements upon opening the door
• Thermocouple break protection cuts power to the heating elements, preventing a thermocouple failure runaway condition
