Single-pass tangential flow filtration (SPTFF) is revolutionizing how tangential flow filtration (TFF) is implemented in biotech, vaccine, blood plasma
- Ability to couple the concentration of product before or after other downstream processing (DSP) steps, consequently optimizing other steps and reducing in-process pool tank volumes.
- Continuous processing in DSP
- Easy integration of the assembled module, allowing plug and play
- Potential reduction of product damage or aggregation due to reduced residence time and
The preassembled Cadence ILC modules do not need a holder. Once the feed port is connected to a pressurized feed source, the module is ready for use. The built-in resistor in the retentate manifold eliminates the need for downstream instrumentation and allows volume reduction of 2 to 4X (or higher), depending on the application.
Similar to other Cadence SPTFF devices, the Cadence ILC utilizes standard Pall T-Series cassettes as the building blocks for the module. These modules are offered with either Delta regenerated cellulose or Omega polyethersulfone (PES) 10 kDa or 30 kDa membranes providing the high flux, high selectivity and low protein binding characteristics associated with these membranes. They are available in a range of size formats to accommodate various processing volumes.
These products utilize proprietary technology, as well as technology licensed from SPF Innovations, and may be covered by one or more patents. See pall.com/patents.
Optimize Economic and Operational Benefits
Enhance downstream processing to increase capacity and reduce costsCadence ILC modules can help to eliminate or reduce the size of intermediate storage tanks and associated cleaning of tanks when used for in-process volume reduction before or after existing steps.
Enable in-process volume reductionDepending on the initial concentration and product characteristics, a volume reduction of 2 to 4X (or higher) can be achieved with minimal instrumentation or system requirements.
Optimize processing of highly shear-sensitive productsProcessing with the Cadence ILC results in only one pass through the pump and module, reducing shear exposure. For products sensitive to pumping, the pump can be completely eliminated by using pressurized vessels to flow the process fluid through the module. Further benefits are achieved by eliminating any mixing or foaming issues associated with the feed tank.
No holder required
Cadence ILC modules are provided assembled, and the cassettes and manifolds are pre-torqued between two end plates so that no extra holder is required.Benefits include:
- Easy connection to a pressure source, like a pump or pressure vessel
- Simplified in-process volume reduction
- Continuous processing enabled by process coupling
- The module feed, retentate and permeate ports are easily connected to the appropriate outlets using clearly marked ports
Innovative SPTFF processing takes place within the Cadence ILC modules. The modules incorporate Pall’s proven T-series cassettes with Delta or Omega membrane and are available in different formats to accommodate various processing volumes (see ordering information).

The Cadence ILC is designed for continuous processing or for in-process volume reduction in various steps in a wide range of applications in the biopharmaceutical industry. These include recovery of antibodies or recombinant proteins, and preparation of samples (concentrating, desalting) before or after column chromatography, and can be implemented in existing facilities facing tank capacity issues or to other process optimization opportunities.
The operating conditions for any single-pass TFF process must be established by performing trials and analyzing results. Pall’s Technical Service Group is available to assist in conducting trials to develop operating conditions necessary to achieve the desired process objectives.
