OTF-1500X-VGB is a vertical quenching tube furnace joints with the atmosphere controlled glove box. The integrated purification system is able to reduce the moisture and humidity to glove box. Users can vertically load the material into the furnace tube without exposure to the oxygen or moisture. The auto electromagnetic sample release mechanism is used to hang/release the sample in/from the hot zone for heat treatment/quenching. The SS304 quenching chamber at the bottom of the furnace is also airtight which ensures a clean and healthy atmosphere suitable for quenching sample from high temperature ( Max. 1500°C) into oil rapidly. It is an ideal tool to study phase transition and microstructure of oxygen & moisture-sensitive materials.

SPECIFICATIONS

System Structure
  • The air-tight joint between the furnace chamber and glove box protects the sample from oxidation in the preparation, transferring processes.
  • Vertical loading of the material with a glove box above the furnace. An electromagnetic release mechanism can release the sample into the quenching chamber at the bottom.
  • Electric gate valve at the bottom of the tube can isolate the heating chamber from the quenching chamber and open for sample drop when quenching is needed.
  • Both Electromagnet sample release flange and the bottom gate valve are with water cooling jackets which help protect Viton sealing gaskets from over-heated.
Input Power
  • AC 208-240V Single Phase, 50/60 Hz
  • 1.5 KW (for glove box); 4KW (for furnace)
Glove-Box
  • Gas purification station is integrated to ensure a low O2 & H2O environment (glove box.
  • Case Material: Stainless steel 304 with 3 mm thickness
  • Chamber dimension: 1200 mm L x 740 mm W x 900 mm H
  • Openable front window panel (tempered glass, 8 mm thick)  for easy device loading

Hydraulic Press
(optional)
Electromagnet Release &
Quenching Media Tank

  • Electromagnet Auto-drop Mechanism for sample easy release under vacuum or atmosphere controlled environment.
  • Hinged plate with a hook & cable can hang the sample in the hot zone for heat treatment.
  • Hinged plate releases when the electromagnet is powered off. Then the sample falls into the quenching tank.
  • Rings attached to the top flange for hanging the quartz block to prevent heat dissipation.
  • Improved top flange design allows easy sample reload without uninstalling all parts of the flange.
  • Bottom flange is connected with a 4″ gate valve ( electrically operated ) via CF-100 adaptor.
  • The gate valve is connected with a quenching media container which is airtight
  • Note: It is suggested to use oil (such as diffusion pump fluid) as quenching agent if quenching under vacuum.

  • In order to obtain accurate temperature inside the tube furnace, you shall calibrate temperature before use, please click here to learn how.
  • How to set up the ceramic tube and vacuum flange for MTI Tube furnace.
  • The tube furnaces with mullite tube are designed for use under vacuum and low pressure
  • Never use graphite crucible in the alumina tube.
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  • Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
  • Vacuum limit definition for all mullite tube furnaces: * Vacuum pressures may only be safely used up to 1400°C
