GSL-1100X is a quartz tube furnace (1~2" diameter) designed for heating up to 1100°C with a programmable temperature controller. The vacuum flanges with valves, vacuum pressure gauge, and quartz tube are included for immediate use. The furnace has a solid round heating chamber that has a more uniform temperature zone and can be set up in both vertical and horizontal positions to meet various applications. SPECIFICATIONS Furnace Structure Energy-saving high-purity Al2O3 fibrous insulation liner Stainless steel shells with adjustable height Adjust three knobs on the back to flexibly change the furnace's vertical position within travel distance (from control box platform to lower end of the chamber): 4.5'' ~ 12'' (without hanger and supporter) Multiple configurations for various thermal processing needs Multi-position adjustable Using as Vertical furnace Knobs for Position Adjustment Power & Current Rating Choice of working voltage AC 110-120V, single phase, 15A, 1.2 kVA AC 208-240V, single phase, 10 A, 1.2 kVA Working Temperature Max. Temperature: 1100°C (< 1 hr) Continuous working temperature: 1000°C Max. Heating Rate: 10°C /min Temperature Distribution Heating Zone Heating Zone Length: 12" (300mm) Constant Temperature Zone: 100 mm within +/- 2°C 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. Laptop, software & WiFi Control (Optional) Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) Labview Based Temperature Control System (MTS01)enables users to edit temperature profiles, manage heat-treatment recipes, and record, and plot data for MTI furnaces. Heating Elements Fe-Cr-Al Alloy doped by Mo Processing Tube Choice of processing tube 1" O.D x 0.87" I.D x 24" L Quartz tube 2.0" O.D x 1.85" I.D x 24" L quartz tube Two fibrous ceramic tube blocks are included to block heat radiation from the hot zone. Quartz blocks (optional) are ideal for clean processing environments and higher vacuum efficiency. Vacuum Flange 1" Flange Set 2" Flange Set Two choices of stainless steel flange with vacuum gauge and valves 2" default flange with 1/4'' Bard fittings, 1/4'' tube feedthrough port (for 1/4" O.D thermocouple insert), and a KF25 vacuum port (click the bottom right picture to see details) 1" flange has no thermocouple insert (click the bottom left picture to see details) Optional: May need a vacuum valve at the vacuum port for 2' Flange Set (click picture left to order) For a fast & better vacuum, we recommend the use of stainless steel pipe (click to order at extra cost), as well as a digital vacuum gauge You may consider ordering a quick connecting flange at an extra cost Click on the furnace picture (lower right) below to see how to insert an external thermocouple; additional furnace accessories are available for purchase. Fitting Ports Both flanges will come standard with 3/8" barbed hose fittings In order to increase the throughput and achieve a high vacuum, you may replace the standard barbed hose fitting with the KF25 adapter (please click the underline to order). For supplying high-pressure gas, you may replace the standard barbed hose fitting with the 304SS 1/4" Swagelok® Tube Fitting x 1/4" BSPP Male Connector (please click the underline to order). Vacuum Pressure 50 m-torr can be achieved by a mechanical pump 10^-5 torr can be reached by molecular pump Pressure Measurement / Monitoring A mechanical Vacuum Gauge is included which measures within a pressure range of -0.1 to 0.15Mpa. Digital Pressure Gauge (optional): A gas-type independent (above 10 mbar) 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 Compliance CE Certified NRTL or CSA certification is available at an extra cost Application Notes Click here to learn the installation of a gas regulator Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bars Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Vacuum pressures may only be safely used up to 1000°C The flow rate for gasses should be limited to 200ml/min for reducing thermal shocks to the tube Please click here to see our typical temperature profile calibration results at various temperatures.
