Büchis Nano Spray Dryer B-90 uses a new technology for particle generation down to the nanometer range from minimal sample quantities at high yields. It is especially designed to evaluate spray drying during the early stages of product development. The modular glass assembly and visible spray process allows quick and gentle drying of a whole variety of applications in small scale, ideal for feasibility studies in R&D laboratories to dry milligrams of powder. The Dryer meets the needs in the pharmaceutical, biotech, medical, food ingredient, chemical, advanced material and nanotechnology. Typical applications are spray drying of aqueous or solvent based solutions, nanoemulsions, nanoparticle suspensions, structural transformations or nanoencapsulations.
