Powders System

Powder System

We provide a full range of filtration and drying systems from small R&D up to larger commercial production scale.

PSL’s Nutsche Filter Dryers are internationally renowned for their efficient and quality designs developed for washing and isolating solids, even in the most difficult production processes.

Early R&D work is critical for any organization thus why our GFD® was designed to be a world-leading process solution for laboratory solid-liquid separation.

The GFD®Lab is a benchtop Agitated Nutsche Filter-Dryer (ANFD), a miniature version of a production filter-dryer, allowing effective filtration and drying with the same reliability and benefits as full size PSL filter-dryers.

It was developed to overcome well-known production challenges faced by manufacturers when using traditional production methods such as Büchner filtration and oven tray-drying. It is the ideal technology to successfully complete scale-up and scale-down activities and obtain predictive performance results.

The GFD®Lab consists of an agitated vessel designed to work under vacuum and under pressure. Its vessel can be made of either glass, stainless steel or Alloy-22, and has a heated jacket for efficient drying. Solid-liquid separation is performed within its unique filtration basket, which can be removed to ease and maximise product collection.
