300C Max. 90mm O.D Tube Furnace with Vacuum Sealed Flanges & Water/Gas Cold Wall for Sample Annealing in High Magnetic Field - GSL-1200X-MH4

0.0/5 rating (0 votes)

Description

GSL-1200X-MH4  is a 90mm OD x 58mm ID  300ºC Max. Tube furnace with vacuum/gas insulated jacket. Such furnace is constructed by SS316L material which has nearly zero magnetic permeability. It is dedicated for use with superconducting high field magnets for material annealing.

SPECIFICATIONS:

Furnace Structure

The tube furnace has three layers
  1. Heating element:  center spiral type SiC filament ( 25 OD x  20 ID x 400 L mm )
  2. SiC sheath: quartz tube  ID 30 × OD 36 mm × 622 mm.
  3. Sample layer:  36 ID × 58 OD × 622 mm L with vacuum sealed flange.
  4. Gas-cooled layer: 58ID × 90 OD × 622mm L to keep outside wall < 30ºC
    customized size tube is available upon request

  • Built in protection for overheated and broken Thermal couple. 
  • Temperature Accuracy: +/- 1 °C
  • K-type thermal couple 
Vacuum Flange (Sold Separately)
  • Special flange for three layers tube is included
  • 1" flange is included for center tube
  •    1" Flange Set            
Fitting Ports (Sold Separately)
  • 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 theKF25 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

  • Limited by vacuum pump
    • 50 mtorr can be achieved by mechanical pump
    • 10^-5 torr can be reached by molecular pump
  •     

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 incorrect reading of gas pressures due to gas-type dependency.

Application Notes

Click here to learn the installation of a gas regulator

  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa
  • 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.
  • 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
