Overview

Minimate™ tangential flow filtration capsules, a Pall Life Sciences product, enable concentration and diafiltration (desalting or buffer exchange) to be performed on the same system with minimal user intervention.

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.

Scalable. Several Minimate TFF capsules may be connected in parallel for increased membrane area. (For more information, contact Technical Service.) Minimate TFF capsules have the same path length and materials of construction as larger Centramate™ and Centrasette™ cassette systems used in pilot and production plants. Predictable performance saves time when scaling up a process.
High product recovery. Optimized flow path design coupled with low protein binding Omega™ membrane minimize non-specific binding.
Disposable, economically-priced device can be dedicated to a single batch or process eliminating the time required for cleaning and validation.
Each Minimate capsule is 100% integrity tested during manufacture to ensure reliable performance. For critical applications, the user can re-test the integrity after initial use. A Certificate of Quality is included with each capsule.
