What is retentate filtration?

Retentate filtration, often referring to Tangential Flow Filtration (TFF), is a process where a fluid is passed tangentially across a membrane, allowing smaller molecules to pass through (permeate) while larger molecules are retained and concentrated (retentate).

Can this unit be scaled up for larger production?

Yes, systems like this often feature identical fluid path lengths, which are designed to enable precise linear scale-up to larger process systems, simplifying process transfer from development to manufacturing.

What maintenance is typically required for this equipment?

Routine maintenance commonly involves cleaning and sanitisation of the fluid path and membrane holders, periodic inspection of seals and connections, and replacement of membranes as needed. Tool-free cassette removal simplifies these tasks.

Is this unit suitable for sterile applications?

Many TFF systems, particularly those with 316L Stainless Steel components, are designed for cleanroom environments and can be sterilised (e.g., by autoclaving or Clean-In-Place/Sterilise-In-Place methods) to meet pharmaceutical requirements.

Typical Specifications

Typical capacity: For this class of equipment, processing volumes typically range from several litres up to tens of litres, depending on the installed membrane area.
Power supply: Units of this type commonly require a standard single-phase electrical supply for ancillary pumps and controls, typically 230V, 50Hz in the UK.
Materials of construction: Commonly, wetted parts are constructed from 316L Stainless Steel or Ultra-High Molecular Weight Polyethylene (PE) for chemical compatibility and durability.
Membrane compatibility: This equipment typically supports a variety of TFF membrane types (e.g., ultrafiltration, microfiltration) and molecular weight cut-offs (MWCOs) to suit specific separation needs.
Footprint: For this size of unit, a compact benchtop or small mobile cart footprint is typical, suitable for laboratory or cleanroom environments.
Operating pressure: Operating pressures for retentate filtration systems commonly range from 0.5 to 5 bar, depending on the membrane and application.
