Minimate™ Tangential Flow Filtration Capsules

Disposable TFF Device for Bioprocessing Applications Accelerates and Simplifies Processing of Up to 1 L

 

  • Efficient processing. Concentration and diafiltration (desalting or buffer exchange) processes can be performed on the same system with minimal user intervention.
  • Achieves high concentration factors in a single step due to the low holdup volume of the device. Process sample volumes up to 1 L or more and efficiently concentrate samples to as little as 5 mL.
  • Minimate TFF capsule includes all fittings and tubing to simplify installation into filtration setups. This versatile, self-contained device works with a variety of positive pressure laboratory pumps.
  • Cost-effective design for non-critical applications. The plastic construction of the Minimate TFF capsule and chemical compatibility of the Omega™ PES ultrafiltration membrane facilitate cleaning and reuse.

Minimate™ Tangential Flow Filtration Systems

Minimate™ Streamlines Laboratory-Scale Concentration, Desalting, and Buffer Exchange Processes

 

  • Plug-n-play design. Plug in a Minimate TFF capsule, add sample, and turn on the pump to start processing. The Minimate TFF system includes all the hardware, tubing, and fittings needed to get your TFF process up and running quickly.
  • High concentration factors. The low system working volume achieved through the use of a conical bottom reservoir and compact design enables high concentration factors from up to 1 L or more of sample to be achieved. Concentrate your sample down to as little as 5 mL.
  • All wetted components are made from low protein binding, chemically resistant, biologically safe materials.
  • Minimal sample carryover. The system has a very low volume and interior fluid contact area. Fluid does not pass through and is not retained in the pump mechanism.
