• ISO-100K is available. 
• Vacuum pressure can reach 50 mTorr by a quality mechanical vacuum pump and 10^^-5 torr by a turbopump. Please click the picture below to see the flange assembling details.

• Standard 1/4‘’ Barbed fittings with needle valves.
• For supplying high-pressure gas, you may replace the standard barbed hose fitting with the 304SS 1/4" Swagelok® Tube Fitting, please click underlined to order.
• Optional: In order to increase the throughput and achieve high vacuum, you may replace the standard barbed hose fitting with the KF25 adapter, please click the underlined to order.
• Optional: You may also consider using the parts to upgrade the furnace

• How to use and maintain Alumina tube in MTI high-temperature tube furnace.
• In order to obtain accurate temperature inside the tube furnace, you need to calibrate temperature before use, please click here to learn how.
• How to set up a ceramic tube and vacuum flange for MTI Tube furnace.
• The tube furnaces with alumina tube are designed for use under vacuum and low pressure < 0.02 Mpa
• Never use graphite crucible in the alumina tube.
• 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 1500°C for the alumina tube.
