Vacuum Seal & Upgrade

• Two stainless steel flanges with a vacuum gauge and valves.
• 1/4" pipe adapters are installed on two ends
• For a fast & better vacuum, suggest you use a stainless steel pipe ( click to order at extra cost ), as well as a digital vacuum gauge.
     

• To achieve a high vacuum, you may replace the standard barbed hose fitting with the KF25 adapter; please click underline to order.
• For supplying high-purity gas, you may replace the standard barbed hose fitting with the VCR Face Seal Fitting; please click underline to order.

Vacuum Level

• 10E-2 torr by a two-stage mechanical vacuum pump.
• 10E-5 torr by a molecular pump.
• Leak rate < 5 mtorr / min.
• Please click the picture below to order separately

Application Notes

Click here to learn more about the installation of a gas regulator.

• The tube furnaces with mullite tube are designed for use under vacuum and low pressure < 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.
• Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
• The flow rate for gasses should be limited to < 200 SCCM ( or 200ml/min )
• Vacuum pressures may only be safely used up to 1300°C
• NOTE The mullite tube shall be considered as a consumable part. We strongly recommend user keep spare tubes in order to ensure the continuity of operation. The tube is not covered by Warranty. Use the link to order more.
