In stock
Item Number: OTF-1200X-VT-100-VTQ
Transported by LTL Freight (Truck)


Upgrade to Eurotherm Temperature controller + USB-to-RS485 cable
OTF-1200X-VT-100-VTQ is split Vertical Quenching Tube Furnace with vacuum sealed 100mm (4")   diameter quartz tube and sealed liquid container, which is designed for quenching sample from high temperature ( Max. 1200oC) to ice water or oil to study material phase transition and microstructure.
(Auto electromagnetic sample release flange is added since 07/21/2016)


 Furnace Structure

  • Double layer steel structure with air cooling to keep case temperature < 65oC
  • Vertical and splittable for easy installation.
  • Sealed liquid container is connected to 4" quartz tube via a gate valve and allow sample drop to liquid container without oxidation

Tube Size and Materials

Heating Zone

  • Heating Zone length:   440mm 
  • Constant Temperature:       150 mm ( within+/- 1oC)

Temperature Controllers

  • 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
  • Built in PID Auto-Tune function with overheating & broken thermocouple broken protection.
  • Over temperature protection and alarm allows for operation without attendant(s).
  • +/- 1 ºC temperature accuracy.
  • One K-type thermocouple.
  • RS485 Communications Port.
Electromagnet Sample Release Flange & Quenching
  • Full automatic electromagnet sample release flange
  • Hinged plate hooks the cable, which pulls the sample.
  • Hinged plate drops when the electromagnet powers off. The sample and the cable fall into the quenching tank.
  • Rings are available for hanging the tube block with cables.
  • Bottom flange is connected with a 4" gate valve ( manual operated ) via CF-100 adaptor
  • The gate valve is connected with a quenching media container in size 400 x400 x 200 H ( mm )
  • Caution: You must use ice water or cooled oil as quenching agent if quenching under vacuum.
