  • Product description: 1800C Lab Compact Tube Furnace for Raw Material

1800°C Programmable High Temperature vacuum tube furnace

AOT-VF-1800C tube furnace feature a chamber with Mitsubishi (Japan) high quality 1900 grade alumina fiber insulation and the famous Kanthal (Sweden) 1900 grade molybdenum silicide heating elements. A double walled steel internal housing helps minimize heat loss to exterior surface.
Furnace operation is controlled by Shimaden (Japan) 40-segment digital controller with built-in RS485 digital communications port and USB adaptor, allowing the user to connect to a PC for remote control and monitoring of the furnace. You can also save or export test results. All our furnaces are CE compliant.


1 Compact, portable and lightweight design.

2 Standard package includes set of stainless steel vacuum sealing flanges with valves and pressure meter.

3 Dual flanges support ensures better sealing and longer tube life.

4 Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot.

5 Multiple atmosphere processes in a single cycle are possible (ex: binder burn out in air and parts sintering under rough vacuum or inert gas environment.)

6 Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.

7 Built-in computer interface.

8  Long life type B thermocouple.



1 Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller's manual) or when the thermocouple is broken or malfunctions.

2 Power failure protection resumes furnace operation right after the point of failure when power is reestablished.


Warning! NEVER fill furnace with explosive gases, including Hydrogen, Carbon Monoxide and Methane.
