System Features
|
-
Aerosol Generation: 2.4MHz Ultrasonic Enhanced Bubbler can "evaporate" target solution with literally no heat generated. An elongated Tee tube wrapped by a heating tape that connects inline with an ultrasonic bubbler can prevent condensing liquid from streaming into the tube furnace and promote the generation of aerosol.
-
Thermal Decomposition: Tube Furnace can be heated up to 1200C maximum. Bypassing the aerosol flux across the temperature and flow rate regulated firing zone, chemical and physical processes may proceed.
-
Nanopowder Collection: an electrostatic precipitator (1.2 L, up to 30 kV) can effectively collect nanoparticles from the carrier gas flow

Application Notes
|
-
A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.
-
Never heat the furnace while the gas 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.
-
Wrapping Aluminum foil to achieve better thermal conductivity.
