1500°C Atmosphere Controlled Quenching Furnace with Glovebox and O2 & H2O Purification System - GSL-1500X-VGB

Please email for lead time
Item Number: GSL-1500X-VGB
Transported by LTL Freight (Truck)
GSL-1500X-50-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 <1ppm.  This helps protect samples from moisture or oxygen exposure during the preparation process. The bulkhead flange ensures a vacuum-tight direct joint between the furnace tube and the bottom of the glove box. Users can vertically load the material into the furnace tube without exposure to the oxygen or moisture. 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 air tight 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 micro structure of oxygen & moisture sensitive materials.


System Structure
  • 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)

  • Gas purification station is integrated to ensure a low O2 & H2O environment (<1ppm) in the 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

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 air tight
  • Note: It is suggested to use oil (such as diffusion pump fluid) as quenching agent if quenching under vacuum.
