The benchtop high temperature muffle furnaces model ACM-MF-72223 features a ceramic shelf for increased load capacity and utilizes thermal-efficient ceramic insulation for optimal energy efficiency, reaching temperatures up to 1400°C. It offers advanced safety mechanisms, such as a door safety switch and a built-in venting system, making it suitable for sensitive microelectronic components. The furnace is equipped with programmable digital controls and over-temperature protection, providing versatility for applications like heat treating and gravimetric analysis.

2. Bench top High Temperature Muffles Furnaces offer heating area and include a ceramic
shelf to double furnace load capacity. Highly thermal-efficient ceramic insulation surrounding
the chamber achieves maximum energy efficiency. Open coil heating elements on both
sides of chamber enable rapid heating with minimal temperature gradient of 1400°C. A built-
in venting system removes contaminants and moisture. Door safety switch provides operator
protection by cutting power to heating elements when door is opened. It features a digital
programmable control and is available with a single stored program of eight segments. All
furnaces utilize a mechanical Over Temperature Protection relay.
These 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 fibre door
includes a chamber plug that
prevents heat loss around the door
by totally sealing when the spring-
loaded door is closed.
Temperature is controlled via PID
automatic control via SCR (Silicon
Controlled Rectifier) power control,

dwell, again with a single display but also with a mechanical Over Temperature Protection
relay. The digital programmable control features 1 stored program with 8 segments, along
with RS232 communications. This microprocessor control features adjustable over-
temperature protection, sensor-break protection, and digital readout of both set point 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. A 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 features built-in racks that allow adjustable positioning of a ceramic
shelf (included), which effectively doubles the working area. It comes with complete with
on/off switch, thermocouple and grounded three-wire cord and plug.
