•      •  One 1/4 gas inlet which allows continuous gas delivery during operation. A gas quartz
           tube (6.35mm O.D) is provided to reach the location of the sample and deliver reactive
          gas to sample directly. (Fig A, B)
•      •  One 1/4 thermocouple feedthrough port allows a 1/4 O.D thermocouple probe to be
           inserted into the chamber and measure the temperature of the sample independently.
           (Fig. C) (Thermocouple is optional. Click here to find one). Four probes electric
           resistance measurement feedthrough also is available upon request. (Fig. D)
•      •  M15 x 1.5mm Thread for both 1/4" feedthrough
•      •  One bored Al2O3 foam refractory block (190Dia *  50mm) is provided. (Fig. F)

•      •  Gas Inlet Tube (O.D 6.35mm, I.D 4.0 mm, L 300mm) is included.    (Since Apr 2016)

   

• 
       •  The sample holder is not provided with the furnace. You may check the link below to order
          the sample holder separately.
•      •  Optional Quartz Thermal Block is available upon request as the refractory block, which can
          help achieve higher vacuum level and avoid potential contamination problems, please order
           Quartz Thermal Block.

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

Pressure Measurement / Monitoring

• 
       •  Mechanical Vacuum Gauge (included as standard accessory), which ranges from -0.1 to
         0.15Mpa.
•      •  Digital Pressure Gauge (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.
  
  

                     

Vacuum Pressure

• 
       •  Vacuum Level is dependent on the vacuum pump used, connected pipe, interior refractory
          block's materials, etc. By using KFD25, stainless steel pipe, MTI's two-stage mechanical
           pump, and KF25 Ball valve, the furnace can achieve vacuum levels below:
•      •  10^-2 torr via mechanical pump within 30 minutes without thermal Block
•      •  10^-4  torr via turbo-pump within 30 minutes with the Quartz Thermal Block at 900C
  
  
•      •  Optional:
•      •  Vacuum pump and pipe are not included, please click on BOLD or picture on the
          optional part below to order.
•      •  For achieving a higher vacuum level, a Turbomolecular Vacuum Pump Station is
         necessary. ( click the bottom left picture to see detailed specs )
•      •  Spare sealing O-ring is available at extra cost ( click 2nd picture to left below )
•      •   KF25 Right-Angle Valve for quick connection to KF25 Bellows (click the picture 3
           below ).
  
  

                                 

    

Temperature Controller

       •  FA-YD518P-AG temperature controller is included.
•      •  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
•      •  Default DB9 PC communication port
  
  

• 
       •  MTS02-Y Temperature control software kit (for YD518P series controllers) + 15" laptop
         package is available at the options bar. Click for the detail information about the MTS02-Y
         software kit.
  
•      •  You may upgrade the temperature controller to the Eurotherm 3504 Temperature
         Controller which is fully compatible with LabVIEW and provides +/- 1°C accuracy.
          This package includes a Eurotherm 3504 programmer, a communication cable (RS485 -
          USB) and a software CD. Click the pic below to view the full spec of Eurotherm 3504

Warning  

Click here to learn the installation of a gas regulator

• 
       •  Tube furnaces with quartz tubes are designed for use under vacuum condition and at low-
          pressure levels <  0.2 bars  ( 3 PSI ). 
•      •  Attention: A two-stage pressure regulator must be installed on the 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 the furnace while the gas release valve is closed and a positive pressure condition
          exists within the furnace chamber. The pressure gauge must be used to closely monitor the
          chamber condition at all times during the heating process; please open the gas release valve
          immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable
          damages.
•      •  A maximum temperature of 1000°C should be imposed on all quartz tube furnaces while
          running a vacuum to ensure safe operation. Temperatures beyond 1000°C could cause the
          quartz tubes to undergo deformations under vacuum.
•      •  The flow rate for gasses should be limited to < 200 SCCM for reducing thermal shocks to the
           tube ( with the output pressure of the gas tank regulated to < 0.2 Bar or < 3 PSI ).
