The system offers a compact 0.5 L working volume with a plug-and-play design that includes a clamp set, pump, and membrane module. This setup enables quick assembly and immediate operation for precise separation or concentration tasks. The design emphasizes low shear force and sanitary construction to safeguard sample quality, making it suitable for delicate protein solutions or bioseparations. Real-time monitoring is supported by a transmembrane pressure (TMP) display, aiding process stability and accuracy.

Best for: researchers needing a small, ready-to-run TFF solution that minimizes handling and preserves sample integrity.

Limitations: as a compact system, it may offer fewer cassette sizes compared with larger benchtop units, which could constrain certain scale-up workflows.

This configuration emphasizes high-performance TFF filtration for protein concentration, diafiltration, desalting, and buffer exchange. It supports multiple configurations and leverages low protein binding membranes to maximize product yield. The 0.5 m² cassette option is particularly suitable for moderate to larger surface area requirements in pilot-scale workflows.

Best for: projects needing higher cassette area without moving to full-scale industrial units.

Limitations: higher-area cassettes may incur greater setup complexity and flow considerations than smaller configurations.

Guiding TFF Cassette & Holder System (0.1 m² / 0.5 m²) 0.5㎡ Holder

Check Price on Amazon

This system combines 0.1 m² and 0.5 m² membrane cassettes with a 0.5㎡ holder, enabling flexible process development from small to mid-scale. It supports protein concentration, diafiltration, desalting, and buffer exchange with low protein binding materials to help retain product integrity. It is a practical choice when transitioning from bench-scale to pilot-scale work.

Best for: teams needing a transitional setup that accommodates multiple cassette sizes within one holder framework.

Limitations: selecting the right combination requires understanding your target flux and recovery goals to avoid under- or over-processing.

Buying Guide

What should I consider when choosing a TFF system?

• Volume and footprint: Choose a system whose working volume matches your typical batch size and fit your benchtop space.
• Cassette size options: Systems offering 0.1 m² and 0.5 m² cassettes provide flexibility for development and scale-up.
• Protein binding: Low protein binding membranes help maximize recovery; assess materials used in cassettes.
• Real-time monitoring: TMP or other sensors support process control and reproducibility.
• Sanitary design: Sanitary-grade pipelines and closed-loop processing minimize contamination risk.
• Ease of use: Plug-and-play assemblies with included clamps and pumps reduce setup time and potential leaks.
• Support for diafiltration and buffer exchange: Confirm the system supports your required sequence of purification steps.

Frequently Asked Questions

1. What is tangential flow filtration used for?
   – TFF concentrates and diafilters biomolecules by flowing liquid tangentially across a membrane, helping to retain larger molecules while washing away impurities.
2. Which cassette size should I start with?
   – For development and small-scale work, 0.1 m² cassettes are a common starting point; 0.5 m² cassettes are useful for higher throughput or pilot studies.
3. Is a real-time TMP display necessary?
   – It improves process control by highlighting changes in transmembrane pressure, assisting in maintaining stable filtration.
4. Can TFF systems handle protein solutions with high viscosity?
   – Some designs perform better with lower-viscosity feeds; verify membrane compatibility and shear considerations for your sample.
5. Do these systems require specialized training?
   – They are designed for straightforward setup, but basic understanding of filtration concepts and safety practices is recommended.
6. Are these systems suitable for buffer exchange?
   – Yes, many configurations support diafiltration and buffer exchange alongside concentration tasks.
