Applications

• Concentrate and desalt proteins, peptides, or nucleic acids (DNA, RNA, oligonucleotides)
• Recover antibodies or recombinant proteins from clarified cell culture media
• Process metal sensitive enzymes and molecules
• Separate (fractionate) large from small biomolecules
• Concentrate viruses or gene therapy vectors
• Prepare samples prior to column chromatography
• Concentrate samples after gel filtration
• Depyrogenate water, buffers, and media solutions

Performance

Designed to work with the Minimate™ TFF Capsule, 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, Masterflex L/S Easy-Load pump head, 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. The tapered bottom and optimally located feed and return ports reduce the system hold-up volume, which allows high concentration factors to be achieved. The reservoir lid seals tightly allowing additional sample volume or diafiltration solution to be drawn directly into the reservoir without the need of a transfer pump. Vacuum is created as filtrate is generated through the TFF device allowing continuous diafiltration to be performed. When it's time to retrieve your sample, simply open the valve on the reservoir outlet and pump out your sample.
