Single Zone Tube Furnace with 6" - 8.5" Quartz tube and Hinged Type Vacuum Flanges (1100 ºC , 24" heating zone) - GSL-1100X-XX-S-UL series

0.0/5 rating (0 votes)



Part Number: GSL-1100X-XX-S-UL

GSL-1100X-XX-S-UL is a ready-to-pass UL/CSA (UL61010 or SPE1000 certification) furnace. It is single heating zone and adapts to various sizes of quartz tube (6" or 8.5" outside diameter). Heating temperature is up to 1100°C. The vacuum flanges with fittings are included. It is widely used for materials or chemical lab to sinter materials and anneal semiconductor wafers under vacuum or other gases condition. Furnace is controlled by an intellegent temperature controller with accuracy +/-1°C and 30 programmable segments.

Application Notes

                     Click here to learn the installation of a gas regulator
  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure <  0.2 bar / 3 psi / 0.02 MPa   ( or   0.12 MPa (absolute pressure).
  • Attention: A two stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  • Never heat  furnace at positive pressure and close outlet valve condition. Once watch pressure gauge on furnace during heating , once pressure is over  3 PSI please open release valve immediately
  • 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
