GFD® – Lab Nutsche Filter Dryers

PSL’s unique lab filter dryers range called the GFD® is an innovative solution to small-scale synthesis / filtration and drying process development. The GFD is a miniature version of a production filter dryer, allowing scalable lab filtration, washing and drying with the same reliability and benefits as PSL’s full size Agitated Nutsche Filter Dryers. The GFD technology supersedes dated methods such as Buchner filtration for feasibility study, R&D work and process development.

The GFD is suitable for any laboratories’ needs with three sizes: MINI LAB (0.1L), LAB (2L) and MAXI LAB (10L). The filter dryer vessel is available in glass borosilicate or metallic option for higher pressure requirements. The GFD includes a unique filtration basket, with a large range of filtration materials and porosities, for a total and easy product recovery.

The GFD works under vacuum and low pressure, has a heated jacket for drying and a high torque/low speed agitator drive with anticlockwise and clockwise rotation for smoothing and ploughing of the cake.
