VACUUM & LOW PRESSURE FURNACES

The best vacuum furnaces either isolate the work zone from the heating elements with a material such as alumina, or use a continuously pumped hot zone with heating elements that have an insignificant vapor pressure at operating temperature.

INERT GAS FURNACES

Inert gas furnaces are vacuum furnaces adapted to tolerate atmospheric gas pressures - the furnace volume must be fully evacuated to eliminate all oxygen.

High Temperature Inert Gas Laboratory Furnace

AIR FURNACES

Air Furnaces - up to 1200oC - very inexpensive.  We have made many configurations - see Customer List

SPECIALTY FURNACES 

We have made some very strange furnaces (see Customer List).  Some of the more common and important of our specialty furnaces are:

1200°C Transparent Furnace

        Gold-coated quartz tube furnace.
        Full optical access to heat-treated sample.
        Observe novel high temperature processes to greatly shorten development time.
        Quickly check quality control issues.
        Monitor brazing and crystal growth.
               Special Capabilities: Optical access to workpiece at temperatures beyond the capability of currently available  transparent furnaces.

Transparent Furnace
 

Fully Transparent Furnace

        Totally clear quartz tube furnace to 700oC.
        Full optical access to heat-treated sample.
        Observe processes to greatly shorten development time.
        Quickly check quality control issues.
        Monitor brazing and crystal growth.
               Special Capabilities: Optical access to workpiece at temperatures beyond the capability of currently available  transparent furnaces.

Fully Transparent Furnace

 

Fast Sample Heating High Temperature Vacuum Furnace

        Sample insertion tube furnace.
        Rapid thermal treatment of experimental samples heated to temperatures up to 1500°C - sample is inserted and removed while furnace stays at temperature.
               Special Capabilities: Cuts sample heat treatment time dramatically relative to standard furnaces.

1500°C Air Box Furnace         (2000)

        Inexpensive high temperature air furnace with replacable elements.
        Annealing/Heat treatment
              Special Capabilities: Low cost, robust, high temperature air furnace whose simplicity of design allows full repair and maintenance by its owner.

Air Box Furnace


High Temperature Furnace        (1999)

       Tube furnace operates up to 2500°C in vacuum/inert gas.
       Perform high temperature materials/optical experiments.
            Special Capabilities: Lowest cost furnace that can achieve very high temperatures.
