Pall® Minimate™ capsules with Omega™ membrane

Reusable 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 Pall Technical Service.) -Minimate TFF capsules have the same path length and materials of construction as larger Pall 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.

Reusable 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.

Pall® Laboratory Manifold

A unique microbiology manifold that allows you to optimize testing without sacrificing cleanliness. With interchangeable components and coupling devices, the manifold takes direction from you.

  • No more “dirty” manifolds: Microbial cross contamination of your sample is a thing of the past. The manifold is designed to fit most laboratory autoclaves by separating into manageable components.
  • Double testing capacity: A larger manifold is at your reach with just a coupler. Modular design allows two manifolds to combine yielding a standard 6-place manifold which can be easily separated for disinfection and/or sterilization.
  • Manifolds that adapt to you: Whether you are right or left-handed, setting up your test workflow is second nature. The components interchangeable and designed with a simple slip fit to the manifold.

Applications

Bioburden testing of filterable products is performed to determine the number of viable and reproducible microorganisms. By recovering organisms on and in a membrane filter, processing efficiency and the microbial quality of a sample can be evaluated to assure that the product is not harmful to the intended recipient.

Detecting spoilage microorganisms are critical for foods and beverages as they may be responsible for the deterioration of sensory qualities (visual, texture, and taste) and may potentially render the product harmful for consumption. Using membrane filtration, detection of these spoilage microorganisms keep contaminated items from reaching the market.

Monitoring for compliance to drinking water standards using Membrane Filtration Technique, determines if there are levels of pathogenic microorganisms in treated water or wastewater. These microorganisms include coliforms such as Escherichia coli (E. coli) and Legionella which are both classified as pathogens.
