|
Constant Temp. Zone
&
Temperature Gradient |
-
50mm within +/-1°C ( If set two zones at the same temperature )
-
70mm within +/-2°C ( If set two zones at the same temperature )

Tube Size
Please select the tube size in the options bar, ( click below to order spare tube ) |
1" quartz tube (25mm O.D x 22mm I.D x 450mm L)
-
Two fibrous ceramic tube blocks are included
-
Quartz blocks (optional) are ideal for clean & Hight vacuum
-
May order flange support to avoid tube rotating.
|
2" quartz tube (50mm O.D x 44mm I.D x 600mm L)
Two fibrous ceramic tube blocks are included for blocking heat radiation from the tube chamber. (Ceramic blocks must be fully inserted into the furnace chamber before heating) |
Vacuum Flanges |
1" flange has no thermocouple insert |
2" and 2.36"(Option) tube flange |
Vacuum Level |
10-3torr (by mechanical pump) |
Fitting Ports
&
Optional Parts |
-
You may need a vacuum valve at the vacuum port
-
You may consider ordering quick connecting flange at extra cost.
-
You may contact us to order the furnace with a vacuum pump and a temperature calibration kit.
|
Pressure Measurement & Monitoring |
-
Standard mechanical vacuum gauge measures within a pressure range of -0.1 to 0.15Mpa is included.
-
OPTIONAL: A gas-type independent (above 10mbar) digital vacuum gauge with a wide range between 3.8x10-5 to 1125 Torr. Aside from greater measurement precision, this gauge reduces risks of chamber explosions caused by the incorrect reading of gas pressures due to gas-type dependency.

Application Notes & Warning
|
-
Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°C
-
Attention: A two-stage pressure regulator must be installed on a gas cylinder to limit the pressure to below 3 PSI for safe operation.
