Lab scale filtration and drying  made easy with Powder Systems Ltd’s Glass Filter Dryer (GFD®) is now available with contained options.

The GFD® is a smaller version of a production filter dryer allowing easy lab 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 any laboratories’ 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 dated methods such as Buchner filtration providing ergonomic and efficient drying.

The GFD® works on a vacuum and has a heated jacket for drying. To achieve  a quicker drying time whilst maintaining a homogeneous product, the GFD® has an adjustable agitator running both clockwise and anti-clockwise for smoothing the cake. The innovative PSL removable filtration basket allows total product collection, without having to dig the cake out of the vessel.

PSL, as a leader of glass filter dryer technology launched the GFD® 2 years ago and have continually improved the features of this revolutionary product. 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 adjusting without effort the agitator height in the slurry or cake in an accurate and repeatable manner thanks to the scale by simple turning the hand wheel.

Contained GFD® options: The Laboratory FilterBox Technology

The FilterBox is a new technology consisting of a GFD® being completely integrated within a PSL isolator, providing high 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.
