Tangential Flow Filtration Systems
Minimate™ TFF System
Designed to work with Minimate™ Tangential Flow Filtration Capsules, this easy-to-use system can process sample volumes up to 1 L or more and efficiently concentrate samples to as little as 5 mL. Subsequent desalting or buffer exchange steps can be run on the same system with minimal user intervention.
The ready-to-use Minimate TFF System includes a Masterflex L/S variable speed peristaltic pump, as well as a 0 - 4 bar (0 - 60 psi) pressure gauge, valves, 500 mL reservoir with magnetic stir bar and stir plate all assembled on a compact drip tray. The use of a peristaltic pump with disposable tubing and fittings minimizes sample cross contamination while providing gentle processing for biomolecules. The reservoir is designed to hold up to 500 mL of sample and provides efficient mixing of product. All wetted parts meet USP Class VI testing. A Centramate™ Tangential Flow Filtration Membrane Cassette Holder can be incorporated into the system to run 0.019m2 Centramate™ cassettes.
Centramate™ 500 S Tangential Flow Filtration System
A graduated 5 L glass vessel provides full visibility and indication of fluid level during operation, so volumes can be closely controlled. Designed with an ultra-compact flow path, the Centramate 500 S system allows users to operate at volumes as low as 170 mL (when using a single Centramate membrane cassette), enabling high concentration factors to be achieved while minimizing operating volumes. Development, time, risk and process volumes are all minimized.
The sanitary, self-venting, fully-drainable design meets the demands of cGMP environments, with full traceability of process-wetted materials. A completely drainable flow path maximizes product yield, and improves cleaning efficiency. Designed through experience, the Centramate 500 S TFF system meets the requirements for cGMP equipment with a comprehensive qualification and documentation package, calibrated process instrumentation and hygienic design. Data from the process instrumentation can be exported to a PC or laptop computer via the USB port on the Centramate 500 S system.
