GFD®Lab
LAB-SCALE AGITATED NUTSCHE FILTER-DRYER

AT A GLANCE
The GFD®Lab is a benchtop Agitated Nutsche Filter-Dryer (ANFD) that efficiently performs laboratory solid-liquid separation processes. It is 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.
Everyday this technology is assisting hundreds of scientists and process engineers around the world to innovate and optimise their unique processes. The GFD®Lab is serving research institutes, laboratories, universities and companies from a wide range of industries globally.
