Please email for lead time
Item Number: VBF-1100X-Q
Transported by LTL Freight (Truck)
  VBF-1100X-Q is a 2" ID vacuum tube furnace with the function of fast heating and cooling ( optional water quenching ) for heat treatment of air-sensitive materials.   The sample will be placed inside half opened and vacuum-sealed tube,  then insert into the pre-heated furnace to achieve fast heating (~ 10oC/S ).  After treatment, the tube will be raised up automatically, then insert into an ice tank for quenching ( quickly cooling ).  This furnace was designed for LPS powder and can be used for quenching all material under vacuum or controlled atmosphere

    • Tube furnaces with quartz tubes are designed for use under vacuum and at low-pressure < 0.2 bars 
    • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.
    • A maximum temperature of 1000°C should be imposed on all quartz tube furnaces to avoid the quartz tubes undergoing deformations under vacuum.
    • The flow rate for gasses should be limited to < 200 SCCM for reducing thermal shocks


    The furnace can upgrade to 4 quartz tubes with rotating mechanism to achieve high throughput sintering
