The GFD laboratory nutsche filter–dryer from Powder Systems Limited (PSL), originally in glass, is now available in metal to allow higher pressures. The laboratory-scale unit can be used for feasibility studies and trials before scaling up to a commercial-scale agitated nutsche filter dryer (ANFD). The stainless-steel or alloy 22 versions allow better replication of the pressures in commercial ANFD.  

The smallest "Mini Lab GFD" laboratory unit has a total volume of 0.3 L that can filter a cake volume up to 0.1 L and is suitable for laboratory-scale trials. The "Lab GFD" size includes a removable filtration basket of 0.01-m² for a cake volume of 0.5 L for small-scale synthesis, and the "Maxi Lab GFD" filters a cake volume of 5 L with 0.05-m² filtration area.
