Established

The proven performance of our mini spray dryer has helped convince countless researchers of the system's capabilities. The Mini Spray Dryer B-290, as the world's leading R&D solution for spray drying, is featured in more than a thousand publications and over 400 patents. 

Established

Cost-efficient

Our spray drying solution is perfect for reproducible powder production on a lab scale. With the industry-favourite spray dryer, you can work with small sample amounts of as little as 5 g to save valuable material. Our spray drying system is characterized by high yields (up to 70%) and low maintenance expenses for a cost-efficient performance. Fast drying processes (up to 1 L/h) enable you to quickly optimize formulations and save time.

Cost-efficient

Convenient

You don't become the world's leading R&D solution in spray drying without offering intuitive handling, fast setup and easy maintenance. Our Mini Spray Dryer B-290 offers you unmatched flexibility with adjustable particle sizes (2 to 25 microns) and with the possibility to scale up to pilot or industrial production. Thanks to the glass assembly design, you gain full visibility of the spray drying process, so you can make faster, better informed decisions during the procedure.
