Büchi Labortechnik AG offers spray dryers in the laboratory scale for more than 30 years. These instruments are used for first trials, feasibility studies, parameter optimization and production of small powder batches. Now Büchi sets a new light with the NEW, unique Nano Spray Dryer B-90. A world novelty for fine particles from minimal sample quantities at high yields!
Whether the requirement is the gentle drying of natural product dyestuffs, the isolation of highly effective pharmaceutical agents or the micro-encapsulation of flavours - the Mini Spray Dryer B-290's and the Nano Spray Dryer B-90's outstanding features greatly extends the number of applications that are possible with a spray drying process.
The Mini Spray Dryer can be extended to a closed-loop condition to safely work with organic solvents under inert conditions. The Inert Loop B-295 is a complementary instrument to work clean the nitrogen in the closed cycle from solvent and permanently monitoring pressure and oxygen concentration.
The Dehumidifier B-296 is the versatile instrument of choice to condition the inlet drying air, to cool the gas for spray chilling or to work in closed mode with water/solvent mixtures.
