VACUUM TRAY DRYERS

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.
