Processing Tube

• 99.8%High purity Al₂O₃ Ceramic, ID: 54mm; OD: 60 mm x Length 850 mm
• Two fibrous ceramic tube blocks are included for blocking heat radiation from inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
  
• You may consider using a tungsten wire to hang up a crucible or sample to quench sample ( click Pic right to learn )
•       

Vacuum Sealing and Valve

• Vacuum pressure can reach 50 mTorr by a quality mechanical vacuum pump and 10^^-5 torr by turbo molecular pump. Please click the picture below to see flange assembling details.
•             
• Optional: You may consider using the parts in below to increase the vacuum efficiency 
• Please click here to order digital vacuum gauge for precision vacuum control up to 10^-4 torr (see picture below and click to enlarge)
• KF25 Stainless steel Bellows 
• KF25 Quick Clamps
• Mechanical pump for 10-2 torr or turbo pumps for 10-4 torr vacuum
•               
• Please click picture below to learn how to quench sample in gas flow and vacuum
• Approach#1: Traditional wire cut and free-falling  ( Fig. 1 & 2 )
• Approach#2: Electromagnetic release and free-falling. (Fig 3 & 4 )

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.

 Quenching operation

• One stainless steel tank is located on the bottom of the furnace to contain quenching liquid.
• One large gate valve is built in bottom tube
• One electromagnet is installed on top flange and hold sample hanging wire up to 500 g
• Touch the release button of the electromagnet on temperature control unit, the sample will drop to the liquid tank.
• Before release, sample must fill argon gas to  5 psi and open gate valve

Power Cable & Plug

• 10 feet length 10-3 AWG heavy duty UL approved power cable is included. Extra length cable can be ordered by click picture below-left
• The plug is not included. Browse our catalog for compatible plugs or obtain one from a local hardware store.
