1100°C Max 8“OD(7.6 L)Vacuum Chamber Furnace 1200X-H8

Product Description

SN1200X-H8 is a compact vacuum furnace. It equips a 7.5" ID x 13.4"L Quartz tube chamber sitting horizontally. Water-cooled stainless steel vacuum flanges with valves are installed to achieve a vacuum of up to10-5 Torr via turbopump. It is designed for calcining or annealing semiconductor wafers (up to 6") under vacuum or various other gas atmospheres with a temperature of up to 1100°C. It also can also be used as a vacuum brazing furnace for fusing small parts.

Gas Inlet and Outlet & Water cooling
  • One gas purging inlet (1/4" hose adapter ) with a valve is on the left side of the furnace

  • The inert gas can be introduced into the chamber via the inlet for purging purposes.

  • If a continuous gas flow is needed, refer to the additional gas inlet and thermocouple probe below.

  • A water cooling jacket has been built inside the flange to protect the vacuum sealing O-tings.

Temperature Control
  • 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

Temperature Accuracy±1℃
Power Supply

208~240V AC, Single phase, 50/60 Hz


Note: Power cable included, but without the plug
