Laboratory Fluid Beds Model 100N/300N

300N Fluid Bed

Applied Chemical Technology's (ACT) 100N and 300N Laboratory Fluid Beds offers the perfect solution for testing or developing chemical products and processes. These versatile units are easy to use and suitable for applications from industrial chemicals, powders to food and nutraceuticals.

With an ACT Laboratory Fluid Bed you can easily experiment with fluidization velocities, operating temperatures, coating methods, drying, agglomeration and cooling curves along with other process variables. The 100N and 300N Laboratory Fluid Beds are also ideal for batch production runs and product evaluation. In addition, all data is directly applicable for scale up to ACT's industrial fluid bed systems.

The 300N is a multi-purpose fluid bed that is 4X larger than the 100N model specifically designed for small to intermediate scale spray coating, granulation and drying of particulates and powders.

100N Fluid Bed

The 100N is a multi-purpose bench-top fluid bed that is designed for small scale spray coating, granulation and drying of particulates and powders.
