OTF1200XIII-PGEP Ultrasonic Spray Pyrolysis 3-Zone Tube Furnace for Nanoparticle Synthesis and AACVD up to 1200°C
The OTF1200XIII-PGEP system is engineered to address the challenges of synthesizing nanoparticles with controlled size, morphology, and microstructure. It is particularly suited for producing nano- and core-shell structured particles through ultrasonic spray pyrolysis and aerosol-assisted chemical vapor deposition (AACVD). This system combines aerosol generation, thermal processing, and nanopowder collection into a streamlined workflow.
Liquid precursors are atomized into fine aerosol droplets by a 1.7 MHz ultrasonic enhanced bubbler, which operates without thermal evaporation. These droplets pass through a three-zone tube furnace with independently controlled heating zones totaling 900 mm in length, reaching temperatures up to 1200°C for short durations and 1100°C continuously. Thermal decomposition and chemical reactions occur within the furnace, converting aerosols into nanoparticles. The system’s tiltable furnace design helps prevent liquid backflow into the atomizing unit.

Configuration & Operating Notes
The system includes an ultrasonic aerosol generator with integrated liquid injection pump and carrier gas flowmeter. A vacuum pump is required for operation of the electrostatic precipitator but is not included. The furnace can be tilted to prevent liquid backflow. Optional accessories include a mass flow controller for gas flow precision, Eurotherm temperature controllers for enhanced accuracy, and software with Wi-Fi control for temperature profile management.
Safety features include built-in over-temperature alarms and arc protection circuits in the high-voltage power supply. Consumable parts such as furnace liners and quartz tubes are replaceable but not covered under warranty.
