Introducing your Smart New Lab Assistant

The GFD®Lab is a benchtop Agitated Nutsche Filter Dryer (ANFD) that efficiently performs laboratory solid-liquid separation processes. It is a miniature version of a production filter-dryer, allowing effective filtration and drying with the same reliability and benefits as full size PSL ANFD filter dryers.

It is designed to overcome well-known production challenges faced by manufacturers when using traditional production methods such as Büchner filtration and oven tray-drying and is the ideal technology to successfully complete scale-up and scale-down activities and to obtain predictive performance results.

The GFD®Lab consists of an agitated vessel designed to work under vacuum and under pressure. The vessel can be made of either glass, stainless steel or Alloy-22 and has a heated jacket for efficient drying. Solid-liquid separation is performed within its unique filtration basket, which can be removed to ease and maximise product collection.

The GFD®Lab is serving research institutes, laboratories, universities and companies from a wide range of industries. The technology is assisting scientists and process engineers to innovate and optimise their unique processes, worldwide.

Features and Benefits

The GFD®Lab is an all-in-one filter dryer designed to comply with Good Laboratory Practices (GLP) for regulated research and development activities. It allows process developers and manufacturers to complete a wide range of processes in one single system:

  • Slurry filtration (solid-liquid separation)
  • Product washing (removing impurities or collecting filtrate)
  • Re-slurry
  • Vacuum drying
  • Product sampling
  • Product discharge

At PSL, we understand your product is valuable. Therefore, maximising your product yield to remain competitive in your sector is vital. The core features of the GFD®Lab are designed to address this crucial requirement.

Upon process completion, your product batch can be easily collected by simply removing the unique filtration basket from the GFD®Lab vessel.

Additionally, the GFD®Lab basket is designed to allow quick and easy changeover of filtration meshes with various pore-sizes and materials (Polypropylene, PTFE, 316LSS, Alloy 22, etc.), hence facilitating multi-product applications.

The GFD®Lab is an innovative agitated nutsche filter dryer with a modular design that enables end-users to interchange vessels sizes from the 010 and 050 series without the need to use a different base frame.

To further enhance production flexibility, the base frame of each GFD®Lab model is also compatible with all available vessel materials (i.e. borosilicate glass, 316LSS, Alloy 22).

Due to the unique GFD®Lab modular design, it is possible to upgrade your 010 and 050 series into a GFD®Lab PLUS model by simply retrofitting a new base frame to your existing vessel. By opting for this upgrade, the additional features allow you to speed-up development activities by automating the controls of your GFD®Lab.
  • Digital display (4″ colour HMI touchscreen)
  • Enhanced user-interface allowing quick navigation
  • Real-time process graph display
  • Design process sequences
  • Optimise and save process recipes (up to 99)
  • Record and export process data

The GFD®Lab PLUS allows users to build bespoke process sequences and optimise process recipes to suit particular process applications.

Production can start at a touch of a button and pre-designed recipes can be initiated with your preferred process parameters (e.g. pressure/vacuum, agitator speed/torque, temperature, duration), thus maximising batch-after-batch reproduction while minimising human error.

Selecting the right process technology at R&D stage is crucial to ensure ultimate scale-up success. PSL’s GFD®Lab product range is designed to streamline scale-up development from early R&D activities to GLP batches and Pilot Plant Production. It is perfectly suited to complete scale-up and scale-down studies as it helps maintain, at every scale, your key process objectives (e.g. product quality, product yield, batch consistency, etc.) and key production parameters (e.g. filtration time, washing time, drying time, etc.).

Being one of the early pioneers of containment technology, PSL has developed the unique FilterBox isolator range which can successfully accommodate every GFD®Lab vessel size (010, 050 and 500 series).

By opting for a GFD®Lab FilterBox, you can rest assured that your workforce is safe-guarded from the most toxic/hazardous compounds and that your product is protected from harmful production environments.

It is predicted that the field of nanotechnology will display exponential growth. Today nanomaterials and nanoparticles are researched and developed in numerous industries: chemicals, pharmaceuticals, electronics, aerospace, construction, agriculture, food or consumer goods to name a few.

Recently, nanoparticles have gained attention due to their potential application for effective drug delivery. One application is the LNPs (Lipid Nano-Particles), which have received significant attention due to their use as the preferred delivery technology for several messenger RNA (mRNA)-based vaccines, developed for the prevention of COVID-19.

Are you trying to optimise your nanoparticle process in your lab? At PSL, we can help and partner with you to improve your down-stream purification, classification, filtration and drying processes. Contact us for more details.
