The GFD nustche filter dryer launched five years ago can now be found in more and more pharmaceutical and drug discovery laboratories around the world. Since the 19th century chemists have used the commonly known method of Buchner filtration, which would then be followed by the use of a vacuum dryer or other method to complete the drying phase.
The GFD technology combines filtration, cake washing and drying all in one step and product is fully recovered through the unique filtration basket.
Due to its direct scale-up abilities, this vacuum lab filtration and drying unit is ideal for feasibility studies and trials before investing in a large scale agitated nutsche filter dryer. The GFD Lab Filter Dryer is now available in glass borosilicate 3.3, stainless steel 316L and alloy C22.
After the filtration and washing of the slurry in a controlled environment, the heated jacket of the GFD is used to heat the vessel for the drying phase. The vessel is rated to temperatures between -25°C and +150°C, and PSL’s preferred temperature control system is the Petite Fleur and Grande Fleur from Huber.
PSL is thrilled to collaborate with Huber on a partnership where PSL can supply the entire package to its customer base consisting of the GFD, Petite Fleur and all the required connectors and ancillaries. The package has been put together to support GFD’s worldwide users by giving them a turnkey solution that is easy to install and operate.
Huber is the technology leader for high precision thermoregulation solutions in research and industry providing high precision temperature control from -125°C up to +425°C. Huber’s extensive product range offers products for laboratory research, process development and manufacturing applications. Huber’s factory is based in Offenburg in southern Germany. Over the years Huber has invested heavily in people and technology to ensure that it stays at the forefront of the precision temperature control market.

PSL will exhibit the GFD-Petite Fleur package at ACHEMA (Hall 5.1, Stand C31) afrom the 15 - 19 June 2015.
The GFD products range from the smallest size ‘Mini Lab’ GFD with 0.002m2 filtration basket for a total volume of 0.3L and can filter a cake volume up to 0.1L; this is a suitable piece of equipment for lab scale trials.
Then the ’Lab’ GFD size includes a removable filtration basket of 0.01m2 for a cake volume around 0.5L for small scale synthesis, when the ‘Maxi Lab’ GFD is used within Kilo-Laboratory for a cake volume of 5L with 0.05m2 filtration area.
