SIUS® Cassettes are the first purpose-built single-use cassettes for tangential flow filtration, delivering unparalleled savings in filter cost, labor cost and buffer use.
TangenX® SIUS® Cassettes
Validated for GMP use, SIUS® TFF Cassettes are delivered ready to use with either ProStream or HyStream membranes, with choice of pore sizes and flow-channel configurations. 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.
Click on the tabs below to explore different features of SIUS Cassettes for process development or commercial manufacturing.
During process development, the aim is to select the most promising membrane candidates while making related decisions regarding feed pressure, transmembrane pressure (TMP) and screen geometry. 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, SIUS PD Cassettes enable linear scale processing over a wide range of operating volumes.

Membrane Surface Areas:
0.01 m2, 0.02 m2, 0.10 m2
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. SIUS® Single-use TFF Cassettes provide reliable cassette-to-cassette consistency, ensuring that processes can scale to commercial production levels.

TangenX® SIUS® Single-use TFF Cassettes are a convenient alternative to reusable cassettes. Delivered ready to use with choice of membrane, pore size and flow-channel configuration, SIUS Cassettes enable cost and process efficiencies while eliminating tedious clean-in-place (CIP) and sanitization steps because increased labor and consumables are not required.

SINGLE-USE EFFICIENCY
Unparalleled process and cost efficiencies
TangenX® SIUS® Single-use Cassettes are the first purpose-built cassettes designed for tangential flow filtration. Deploying these innovative cassettes can help reduce filter cost by 80%, reduce labor costs by 50%, and reduce buffer and water usage by 75% when compared to traditional reusable cassettes.

FLEXIBLE
Multiple channel configurations
Turbulence at the membrane surface minimizes fouling. The result is an increase in performance with a higher permeate flux. SIUS® Cassettes are offered in three 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.
A medium channel or L-screen is offered in all TangenX SIUS cassette formats. The screen creates turbulence at the membrane's surface ensuring outstanding permeate flux with minimal fouling. This channel configuration requires the lowest pumping rate and yields the highest cross flow velocity. This type of channel is best suited for clarified feed streams over a wide range of viscosities.
A coarse screen, the E-screen is offered in all TangenX SIUS cassettes. The screen geometry of this single-use cassette can process feed streams with a higher viscosity and reduce the overall pressure drop. It is scalable from 100 cm2 to 2.5 m2, packaged, sanitized and compatible with existing cassette holders and FPIs. This type of channel is best suited for processes with viscous, high concentration feed streams.
An open channel or J channel is offered in all TangenX SIUS cassettes. A 0.5 mm flow spacer separating the membrane creates an open feed flow channel. This type of channel creates the least amount of turbulence while still minimizing fouling. It also requires the highest pumping rate to pass particulates. This type of channel is best suited for unclarified feed streams and is used for processes such as cell harvest operation.
