Product Detail
1100C Vacuum Chamber Furnace (7.5"IDx8.5"L, 7.6 Liter ) with 30 Segment Programable Temperature Controller - VBF-1200X-H8
Working Temperature<=    1000 °C continuously Max.  1100 °C,  < 30 minutes 
Heating Element  High quality Ni-Cr-Al resistance wire as heating element and can be heated up to 1200°C.
Quartz tube size &  Effective Heating Area



  Tube size: 8" O.D. x 7.5" I.D x 13.4" L.   Heating area: 7.5" ID x 8.5" Depth (7.6Liter)   Quartz tube is replaceable  ( click picture left to order spare tube )    
Temperature controller  Built in 30 segments programmable digital temperature controller provides the precision control of heating rate, cooling rate and dwell time. Please click the pic to enlarge.Note: To achieve fully temperature computerization please order a set of MTS-02 control module. If you order the control module with the furnace we will install and test it before we ship out the product. We recommend you order computer (laptop) from us. More information please click here.
Uniformity+/- 2°C
Vacuum flangeStainless steel vacuum flange with double high temperature silicone O-ring at front door. One needle valve built on the flange is for gas inlet. One KF25D port on left side of furnace  is for connection with vacuum pump. The water cooling jacket has been installed in the flange. The inlet and outlet ports are located on the left side of the furnace for connecting to the water chiller through two 12mm dia. polyurethane tubes (the water chiller needs to be order separately. Please click here to review detail info of the water chiller.) The Ceramic Thermal Block must be placed inside the chamber during operation to avoid the silicone o-ring being damaged by the heat radiation when the temperature is higher than 300°C Optional: If you intend to apply high vacuum, please order the quartz thermal block to replace the ceramic block. The quartz thermal block has fibrous alumina inside quartz cover and provide excellent clean environment and vacuum pressure. 
Digital Vacuum Gauge & KF25 Fitting


Digital vacuum meter with wide range up to 10-4 torr is included for vacuum pressure measurement. KF25 Vacuum Fitting with KF25 Right-Angle Valve for quick connection to KF25 Bellows.
Vacuum pressure

Vacuum Level is depended on vacuum pump,  connected pipe, inside refractory block's materials etc.  By using KFD25, stainless steel pipe, MTI two stage mechanical pump and KF25 Ball valve, the furnace can achieve vacuum level as the follows:

10 m- torr(10-2 torr)via two stages mechanical pump within 30 minutes without Ceramic Thermal Block. 60 m- torr(6x10-2 torr)via two stages mechanical pump within 30 minutes with Ceramic Thermal Block at 900C. Vacuum leak rate at room temp. ≈ 125 mtorr/hour Optionals: Vacuum pump  and pipe are not included, please click bold order it separately. If you want to achieve higher vacuum (<10-5 torr or better)  you must  Use Turbo-molecular Vacuum Pump Station  Use Quartz Thermal Block


Gas flow and pressureThere is a gas inlet (1/4" house adapter )  with  a Valve on left side of furnace ( see picture left ) Inert gas and oxygen gas flow can be achieved via the inlet . (Attention: MTI does not recommend using our products under hazardous conditions. We are not liable for any damage incurred under hazardous conditions. If you intend to use hydrogen, however, we feel it's prudent to place the furnace under fume hood.) Max. gas pressure shall be less than 1.2 atm. You may choose gas mixer to deliver multi-gases to control gas composition and flow-rate (please order separately).
