Key Features of the Büchi B-290

​

• Low Sample Requirements:

      Operates efficiently with small sample volumes, ideal for R&D with limited or valuable API.

• Precise Process Control:

      Features adjustable inlet temperatures up to 220°C, aspirator airflow, and a feed rate control system for reproducible and            optimized drying conditions.

• Broad Solvent Compatibility:

      Supports both aqueous and organic solvents through its standard and inert loop systems, enabling a wide range of                      applications.

• Particle Engineering:

      Control particle size and morphology for specialized applications.

• Efficiency:

      The system’s design ensures fast changeover between batches and minimizes the risk of cross-contamination.

Applications in Pharmaceutical and Material Sciences

​

Our expertise enables us to leverage spray drying for a variety of critical functions, including:

• Enhancing the solubility and bioavailability of poorly soluble compounds through amorphous solid dispersions.

• Generating inhalable particles and microencapsulated actives.

• Stabilizing sensitive molecules and biopharmaceuticals.

• Formulating nutraceuticals, fine chemicals, and specialty materials.​

​

Integrated Analytical Support

​

We offer seamless integration with our in-house material characterization techniques to provide a comprehensive solution:

• XRPD for crystallinity and phase identification

• Thermal analysis (DSC, TGA)

• Moisture profiling (DVS)

• Particle size and morphology analyses
