The BUCHI Mini Spray Dryer S-300 is a fully automated laboratory spray dryer for producing fine powders in R&D, formulation and process development. It handles aqueous, organic and corrosive feeds and produces particles across a wide size range with a high yield thanks to its coated cyclone and optimized gas flow. Auto Mode automates heating, conditioning and shutdown, while remote monitoring and method programming via the mobile app and PC keep runs reproducible and hands-off.
