The optional PC control module

Optional Eurotherm 3000 

Processing Tube

• 99%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 the 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 the flange assembling details.
•             
• Optional: You may consider using the parts below to increase the vacuum efficiency 
• Please click here to order a 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 turbopumps for 10-4 torr vacuum
•                  

Electromagnet Sample Release Flange & Quenching
         

• Full automatic electromagnet sample release flange
• The hinged plate hooks the cable, which pulls the sample.
• The 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.
• The 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 a quenching media if quenching under a vacuum.
