GSL-1100X-50-LVT vacuum tube furnace is a ready to pass UL or CSA certification (UL61010 or SPE1000) on customer side at customer cost tube furnace for heating samples up to 1100°C.
The right side of the furnace system is composed of a KF25 Gas Outlet with Digital Vacuum Gauge connected to a 226L/m Mechanical Pump with Exhaust Filter.
The 1/4'' barbed gas inlet on the left, allows the furnace to heat samples in vacuum up to 1E-2 Torr or with flowing gas.
In addition, an OMEGA 1/4’’ O.D K Type Thermal Couple is included for attaching to the left flange.
It can be inserted into the tube to accurately measure the sample’s temperature by the readout from the OMEGA Calibrator.
Built-in precision temperature controller will provide up to 30 segments of heating and cooling steps with +/- 1 °C accuracy.

Application Notes
•Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.12 MPa (absolute pressure). •Attention : Due to the high pressure gas output from the gas cylinder, it is necessary to install the gas pressure regulator with it to reduce the output pressure, avoid overpressurize the furance chamber and ensure a safe operation.Click here to learn the installation of a gas regulator. •Vacuum limit definition for all quartz tube furnaces : * Vacuum pressures may only be safely used up to 1000°C •The flow rate for gases should be limited to < 200 SCCM (or 200ml/min) for reducing thermal shocks to the tube •Please click here to see our typical temperature profile calibration results at various temperatures. •In order obtain accurate temperature inside tube furnace, please click here to learn how to calibrate the temperature on your own. •How to set up tube and vacuum flange for MTI tube furnaces.
