GSL-1000X-20 is a 20 mm OD mini tube furnace designed for processing small samples up to 1000oC under a vacuum or controlled atmosphere. The stainless steel vacuum flanges with valves and quartz tubes are included for immediate use. The built-in precision temperature controller can program up to 30 segments of the heating, dwelling, and cooling steps. The furnace and controller are separatable, which can be set up in vertical or horizontal positions to meet various applications such as sample heating, VLS, CVD, and gas analysis.

Heating Rate: 10°C /min Heating Zone Heating Zone Length: 2.16" ( 55mm) Constant Temperature Zone: 0.8" (20mm. +/- 5ºC)The furnace can be placed in either a horizontal or vertical position Temperature Controller PID automatic control and auto-tune function 30 programmable segments for precise thermal processing Built-in protection for the over-heated and broken thermocouple. Temperature Accuracy: +/- 1 °C K type thermocouple Heating Elements Fe-Cr-Al Alloy doped by Mo Protective Cover A specially made protective shield is mounted on the furnace for scald protection at high temperatures (800°C+). Processing Tube Fused quartz tube: 20 mm OD x 17 mm ID x 192 mm Length is included (Pic.1) Two ceramic tube blocks are included for blocking heat radiation generated from the tube center. (Pic.2) For high vacuum, please choose quartz block as Pic. 3 The small crucible may be used for tube furnace. Pic.1 Pic.2 Pic. 3 Pic.4 Vacuum Flange One end is KF25 quick clamp flange is included without valve Another end is screw tighten flange with 1/4 gas inlet Vacuum Pressure 20 m torr can be achieved by the mechanical pump Please click the picture below to order a vacuum pump Dimensions Shipping Weight 50 lbs Warranty One-year limited warranty with lifetime support (Consumable parts such as processing tubes, and O-rings are not covered by the warranty, please order replacements at related products below.) Compliance CE Certified NRTL(UL61010) or CSA certification is available at extra cost. Operation Instructions Application Note The furnace is separable with a controller and easy to replace The furnace can be used a vertical position as the picture below The furnace is small enough to put into the glovebox through an airlock chamber
