Heating chamber | 150 x 150 x150 mm |
Heating Elements | 4 pcs of U-shaped 1800 grade MoSi2 |
Temperature Controller | PID automatic control via SCR power control with phase angle fired, current limiting resistor. 30 programmable segments for precise control of heating rate, cooling rate, and dwell time. Built-in over-temperature ALARM and protection allow for operation without an attendant. +/- 1 ºC temperature accuracy. RS485 Communication Port |
Processing Tube and Crucible | 99.5%High purity Al2O3 Ceramic ID: 50 mm; OD: 40 mm x Length 1000 mm Two fibrous ceramic tube blocks are included for blocking heat radiation from inside the tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating) 4 alumina crucibles of 15mm Dia x 15 mm H are included |
Vacuum Sealing Flanges | One pair sealing flange with double silicone high-temperature O-ring is included. Two SS needle valves and one dial vacuum gauge are installed with a flange for immediate use. 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. |
Fitting Ports | Standard 1/4‘’ Barbed fittings with needle valves. For supplying high-pressure gas, you may replace the standard barbed hose fitting with the 304SS 1/4" Swagelok® Tube Fitting, please click underlined to order. Optional: In order to increase the throughput and achieve high vacuum, you may replace the standard barbed hose fitting with the KF25 adapter, please click the underlined to order. Optional: You may also consider using the parts in below to increase the vacuum efficiency |
Vacuum Level | 50 m-torr can be achieved by a mechanical pump 10^-5 torr can be reached by molecular pump The vacuum pump is not included, please order separately |
Net Weight | 150 kg (330 lbs) |
Shipping Dimensions | 48" x 40" x 67" |
Shipping Weight | 200 kg (440 lbs) |
Warranty | One-year limited warranty (Consumable parts such as processing tubes, O-rings and heating elements are not covered by the warranty, please order the replacement at related products below.) |
Warning
| MoSi2 heating element is used in high temperatures under an oxidizing atmosphere. During the oxidizing process, the SiO2 protective film is formed again the heating element from melting during sustained use. The MoSi2 heating element must not be used in temperatures between 400 C and 700 C for a long time, otherwise, the element will be cremated under the strong oxidizing atmosphere at low temperatures. |
Application Notes | Vacuum pressures may only be safely used up to 1500°C The tube furnaces with alumina tubes are designed for use under vacuum and low pressure < 0.12 MPa (absolute pressure) The flow rate for gases should be limited to < 200 SCCM for reducing thermal shocks to the tube |
