First purpose-built, single-use cassettes for tangential flow filtration (TFF)

TangenX™ SIUS™ Single-use TFF Cassettes deliver the performance of reusable cassettes with single-use convenience at a fraction of the cost. Pre-sanitized and packaged with 0.2M NaOH, the cassettes are engineered with optimized channel geometry and enhanced device rigidity to ensure that hydraulic performance is maintained during processing and scale-up. 

TFF systems are typically used in a process and then cleaned between uses with a clean in place (CIP) operation. This requires a significant investment in system capacity, raw materials, energy, and time. Validated for GMP use, TangenX™ SIUS™ Single-use TFF Cassettes are a convenient alternative delivered ready to use in two industry standard format footprints. They are available using ProStream or HyStream membranes, with a complete range of pore sizes and flow-channel configurations.

Ideal for process development

During process development, the aim is to select the most promising membrane candidates while making related decisions regarding feed pressure,  trans-membrane pressure (TMP) and screen geometry. TangenX™ SIUS™ PD Single-use TFF Cassettes save valuable time and resources by eliminating cleaning cycles between experiments. Designed for processing volumes from tens of milliliters to several liters, TangenX™ SIUS™ PD Cassettes enable linear scale processing over a wide range of operating volumes.

  • Unparalleled cost savings- 80% reduction in labor cost, 50% reduction in labor cost, 75% reduction in buffer use
  • Scalable - optimized channel geometry and enhanced device rigidity ensures hydraulic performance is maintained during scale-up
  • Highly consistent - rigorous QC lot release testing is undertaken for both air integrity and hydrodynamic performance
  • Compatible with holders from major suppliers (Millipore, Pall, Sartorius)
  • Validated for GMP - Validation Guide and Certificate of Compliance provided to meet regulatory guidelines

To ensure fit with cassette holders from other manufacturers, TangenX™ SIUS™ PD Single-use TFF cassettes are offered with two different notch patterns at the end of the cassette.

Ideal for scale-up and large-scale commercial applications

When the primary membrane candidate has already been chosen as  a process parameter, the production method needs to be verified and production materials produced for toxicology or pre-clinical trials, and ultimately for large-scale commercial production. TangenX™ SIUS™ Single-use TFF Cassettes provide reliable cassette-to-cassette consistency, ensuring that processes can scale to commercial production levels.

Process volume and membrane area determine scale-up from TangenX™ SIUS™ PD to SIUS™ Single-use TFF Cassettes.

Tangential flow filtration cassettes create turbulence at the membrane's surface and minimize fouling . The result is an increase in performance with a higher permeate flux. TangenX™ SIUS™ cassettes are offered in two different channel configurations to best suit the application. The channel configuration refers to the type of turbulence promoter incorporated into the feed channel of a cassette. 

L Screen

A medium channel or L screen is offered in all TangenX™ SIUS™ cassette formats and creates turbulence at the membrane's surface ensuing outstanding permeate flux with minimal fouling. This channel configuration requires the lowest pumping rate and yields the highest cross flow velocity of the two types offered. The feed flow channel in the TangenX™ SIUS™ cassette has been optimized to provide high turbulence at the membrane's surface, while minimizing the pressure drop (Delta P). This type of channel is best suited for clarified feed streams over a wide range of viscosities.

J Channel

An open channel or J channel is offered in all TangenX™ SIUS™ cassettes and consists of an 0.5mm flow spacer separating the membrane creating an open feed flow channel. This type of channel creates the least amount of turbulence at the membrane's surface while still minimizing fouling. It also requires the highest pumping rate and can not match the cross flow velocity of the screen channel cassette. It does however possess the ability to pass particulates, such a cells or cell debris through the channel without plugging. This type of channel is best suited for unclarified feed streams and is used for processes such as a cell harvest operation.
