         Optional: PC interface & software  Eurotherm temp. controllers

• Vacuum sealed stainless steel flanges with double high-temperature silicone O-ring are included to achieve high vacuum  (Usually 10-2 torr by mechanical pump and 10-4 torr by molecular pump ).  The vacuum pump is not included
• The right-side flange is hinge-type and  KF25 vacuum port. KF25 Vacuum Right-Angle Valve and 1.2 meters long KF-40 Flexible Stainless Steel Vacuum Hose ( Bellows ),  are included.  One 1/4" diameter feedthrough port is built-in one flange for insert a thermal couple to calibrate furnace temperature. ( please order 36" length x 1/4"dia  K type

• Furnace:  1300 L x 680 W x 920 H,  mm
• Sliding Table: 600mm L
• Note: You must put the furnace and sliding table on a flat surface.  Must make good alignment between the sliding flange and furnace ( We ship sliding table and furnace separately

• CE Certified
• NRTL or CSA certification is available upon request

• Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bar / 3 psi / 0.02 MPa
• 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 overpressurizing 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
