Powder Systems Ltd (PSL), Liverpool, UK, recently launched its GFD® bench-top nutsche filter dryer which has been designed to overcome challenges with commonly used methods of Buchner filtration and oven drying. The unit performs laboratory process development tasks combining filtration, solids isolation, cake washing and vacuum drying all in one step. The final product is also fully recovered through a removable filtration basket, which is said to be unique.

 

With new features such as data logging, accurate control of the agitator speed and recipe input, the GFD can be autonomous and run processes without human intervention. Users can save all of the process data and export for further analysis and repeatability. Process control and automation, even of the agitator raise and lower mechanism, is performed via the HMI/PLC display for a direct and easy product usability. Now more compact and providing enhanced ergonomics, the GFD can be integrated into fume hoods while maintaining good process visibility, batch homogeneity and reduced product exposure. Thanks to its direct scale-up abilities, the unit is well suited for feasibility studies and trials before investing in a large-scale agitated nutsche filter dryer. www.powdersystems.com
