In RESS, supercritical CO2 fluid will rapidly lose its solvent power of extract as arranged to pass through a short nozzle with volume expansion and gasfication. The target extrat originally dissolved in the solution will then precipitate as fine particles. And the CO2 is recycled into liquid from gas state.

Features 

1. No heat generation, suitable for thermo-sensitive substances
2. Effective formation of micron-scale powder at low temperature and high pressure
3. Particle size controllable
4. No solvent residue, therefore eco-friendly

Applications

1. Novel drug
2. Optoelectronic material such OLED molecules, solar cell particles etc
