Quartz Tube & Effective Heating   | |
Vacuum Flange
| - Stainless steel vacuum flange with dual high-temperature silicone O-rings with water cooling jacket
- One 1/4 gas inlet and one gas outlet with needle valves.
- One bored Al2O3 foam refractory block (190Dia x 50mm) is provided
- K25 port is built-in for connecting to the vacuum pump
- Mechanical Vacuum Gauge (included as standard accessory), which ranges from -0.1 to 0.15Mpa
|
Water Cooling
| - A water-cooling jacket has been built inside the flange to protect the vacuum sealing assembly from melting at over 200°C. 16L/min water flow required.
|
Temperature Controller
  | - NRTL certified digital temperature controller is included
- Proportional–integral–derivative control (PID control) and auto-tune function
- 30 segments programmed with ramping, cooling, and dwelling steps
- Built-in over-temperature alarm and thermocouple failure alarm
- +/- 1 ºC temperature control accuracy
- THE Default DB9 PC communication port included for connecting to PC
- Eurotherm Temperature Controller is available at the extra cost with +/-0.1°C accuracy
|
Options
| - Digital Pressure Gauge (optional) A gas-type independent(above 10mbar) digital vacuum gauge with a wide range between 3.8 x 10-5 to 1125 Torr. (Click Pic. 1 to order)
- You may choose a gas mixer to deliver multiple gasses with control over gas composition and flow rate (click pictures below to order separately).
- The furnace can be modified into a faster heating and cooling furnace ( Pic. 3)

Vacuum Pressure
| - Vacuum Level is dependent on the vacuum pump used, connected pipe, interior refractory block's materials, etc. By using KFD25, stainless steel pipe, MTI's two-stage mechanical pump, and KF25 Ball valve, the furnace can achieve vacuum levels below:
- 10-2 torr via mechanical pump within 30 minutes without thermal Block
- 10-5 torr via turbo-pump within 30 minutes with the Quartz Thermal Block at 900C
- Optional:
- The vacuum pump and pipe are not included, please click Pic.1 to order
- For achieving a higher vacuum level, a Turbopump Station is necessary. (click Pic.2)
- Spare sealing O-ring is available at extra cost (click Pic.3)
- KF25 Right-Angle Valve for quick connection to KF25 Bellows (click Pic.4)

Warning  Click here to learn the installation of a gas regulator
| - 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
