Warrant

• 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.)
  
• ATTENTION: Any damages caused by the use of corrosive and acidic gases are not under the coverage of MTI One Year Limited Warranty

• Quartz tube furnace is 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 pressures in the furnace shall be used below 1000°C under vacuum processing
• The furnace can be used for brazing of two flat samples via top dead weight under vacuum at <1000°C
