Nano Spray Dryer B-90 HP

Small particles, small samples, high yields

With the Nano Spray Dryer B-90 HP, gently process the smallest sample amounts into submicron particles with minimal product loss. The user-friendly system improves productivity in areas where small particles make a big difference.

  • Evaporation capacity: 0.2 L / h H2O (higher for organic solvents)
  • Final particle size: 200 nm - 5 μm
  • Yield: up to 90%

Small particles

If you would like to produce small particles (0.2-5 µm) in a safe and controlled manner, then our Nano Spray Dryer B-90 HP fits your needs. With the Nano Srpay Dryer B-90 HP, you gain a larger surface contact area due to reduced particle size. The gentle process conditions help preserve molecular activity in your compounds of interest.

Small particles

High yields

The piezzo driven spray head optimizes your productivity and makes your system easier to handle. If you are trying to improve product yields, our patented airflow systems for gentle solvent evaporation combined with an electrostatic particle collector can help you achieve higher recoveries. For most-efficienty use of your spray dryer, use the Auto-Stop mode to prevent the machine from running empty. 

High yields

Small samples

Our solution enables you to process very small volumes (<2 mL) of sample quickly and efficiently. Limit any product loss thanks to efficient particle recovery with our Nano Spray Dryer B-90 HP. Should you require any further support, you can easily access our vast application database to help improve your spray drying process. 

Small samples


    • Working in inert atmospheres
    • Condensation of solvents
    • Feedback of inert gases
    Spray drying organic solvents
  • The spray head was designed to spray dry small samples (< 2 mL) and to be easy to assemble and to clean.

    User-friendly spray head
  • The 17‘000 V tension applied to the collecting electrode allows the efficient recovery (up to 90%) of smallest particles.

    Efficient collecting electrode
  • Nebulizers in the sizes small, medium and large allow for the finding of the perfect balance between small particles and high throughput (up to 200 mL/h).
