Powder Systems says that this will allow easy laboratory scale filtration and drying with the same reliability and benefits as full size agitated nutsche filter dryers.This small scale filter dryer is suitable for all laboratory needs and is available in three filtration area sizes: MINI LAB (0.002m² - 0.5L), LAB (0.01m² - 2L) and MAXI LAB (0.05m² - 10L). Its technology supersedes Buchner filtration, providing ergonomic and efficient drying.The GFD works in a vacuum and has a heated jacket for drying. To achieve a quicker drying time while maintaining a homogeneous product, the GFD has an adjustable agitator running both clockwise and anti-clockwise for smoothing the cake. The PSL removable filtration basket allows total product collection, without having to dig the cake out of the vessel.PSL, a leader of glass filter dryer technology, launched the GFD two years ago. The new generation of Glass Filter Dryers benefit from new design features including a control/drive with RPM reading, O-ring groove in the glass body to ease fitting of the basket and a mechanical agitator height adjustment system. The latter allows easy adjustment of the agitator height in the slurry or cake in an accurate and repeatable manner.The GFD also offers Laboratory FilterBox Technology. The FilterBox is a new technology consisting of a GFD being completely integrated within a PSL isolator, providing a high level of containment when handling highly potent APIs and other highly active or cytotoxic compounds. The FilterBox achieves containment to nanogram levels, protecting both the product and the operator during operations including charging, sampling, filtration, drying and discharging. The GFD FilterBox is an acrylic glovebox surrounding PSL’s MINI LAB or LAB Glass Filter Dryer. Larger options include the MAXI LAB GFD which can be incorporated within a full scale isolator in stainless steel for Kilo Lab or pilot plant applications.
