What Is the Best Automated Tangential Flow Filtration System for GMP Bioprocessing?

Comparing Automated TFF Systems, Competitive Strategies, Product Pipelines and Growth Opportunities

There is no single automated tangential flow filtration (TFF) system that is the best choice for every GMP bioprocessing application.

The right platform depends on batch volume, molecule type, membrane format, process scale, automation requirements, single-use strategy, data integrity requirements, and future commercial capacity.

However, for companies looking specifically for highly automated, scalable TFF designed for modern biologics manufacturing, Repligen’s KrosFlo RS series is among the strongest systems to evaluate. The platform is designed for automated ultrafiltration and diafiltration (UF/DF), supports batch volumes from 35 mL to 2,000 L, and is positioned for GMP manufacturing, including applications such as mRNA and gene therapy.

The broader KrosFlo portfolio also provides a development-to-manufacturing platform, ranging from the KR2i system for 2 mL to 15 L processing through pilot-scale and GMP manufacturing systems.

But the real question for biopharma manufacturers is bigger:

Which TFF platform provides the best combination of automation, GMP readiness, scalability, process control, technology flexibility, and long-term commercial value?

That question is becoming increasingly important as biologics, biosimilars, cell and gene therapies, and RNA-based medicines expand manufacturing complexity.

Why Automated TFF Is Becoming a Critical GMP Manufacturing Technology

Tangential flow filtration is used across bioprocessing for operations including:

  • Concentration
  • Buffer exchange
  • Diafiltration
  • Desalting
  • Purification support
  • Product recovery
  • Viral vector processing
  • mRNA and RNA processing
  • Monoclonal antibody manufacturing
  • Vaccine manufacturing

Traditional TFF operations can require substantial operator involvement to monitor pressure, flow, transmembrane pressure (TMP), concentration, and process endpoints.

Automation changes the value proposition.

An advanced automated system can potentially provide:

More consistent process control + reduced manual intervention + improved reproducibility + electronic data capture + easier scale-up + stronger process monitoring.

For GMP manufacturers, this matters because process consistency and data integrity are commercial as well as technical priorities.

FDA’s current biologics regulatory infrastructure reflects the scale and diversity of products requiring controlled manufacturing. The FDA Purple Book contains information on FDA-licensed biological products regulated by both CDER and CBER, including biosimilars, interchangeable biologics, cellular and gene therapies, hematologic products, allergenic products, and vaccines. The database continued to publish monthly updates through August 2026.

FDA also recorded 18 biosimilar approvals for 10 reference products in 2025, highlighting continued biologics competition and the resulting need for efficient and scalable manufacturing infrastructure.

The KrosFlo KR2i is designed for research and process development rather than large-scale commercial manufacturing.

It supports UF/DF batch volumes from 2 mL to 15 L and includes 13 automated process control modes. The system can work with hollow-fiber filters and flat-sheet cassettes.

Its Automatic Back Pressure Valve technology is designed to automate TMP control and reduce hands-on operator involvement during TFF processing. Repligen also states that its KMPi software platform offers an optional 21 CFR Part 11 package for validated GMP processes.

Best Fit

Process development laboratories that need automation and want greater continuity with a broader TFF platform family.

The Most Important Buyer Criteria for GMP TFF Systems

The word “automated” should not be the only selection criterion.

A serious GMP procurement decision should evaluate at least eight areas.

1. GMP and Data Integrity Readiness

Ask:

  • Is the automation architecture suitable for validated operations?
  • Is electronic data capture available?
  • Is audit trail functionality available?
  • Does the software support user access controls?
  • Is 21 CFR Part 11 functionality available where required?
  • What validation documentation does the supplier provide?

A system can be highly automated but still create substantial validation work for the manufacturer.

2. Scalability

The ideal platform should support a rational development pathway.

A manufacturer should ask:

Can process parameters developed at small scale be transferred to pilot and commercial manufacturing without rebuilding the process strategy from the beginning?

Repligen positions its KrosFlo family as a standardized platform spanning development through larger-scale processing, with shared automation and process-control concepts across systems.

For buyers, scalability can reduce both technical and commercial risk.

3. Process Automation and Control

Evaluate automation for:

  • TMP
  • Feed flow
  • Permeate flow
  • Pressure
  • Diafiltration
  • Concentration
  • Endpoint control
  • Alarms
  • Data logging
  • Recipe management

Repligen’s KR2i, for example, includes automated process modes and automatic back-pressure control intended to support more consistent TMP management.

The strongest future platforms will increasingly move toward:

Automation → real-time monitoring → predictive process control.

4. Molecule and Modality Compatibility

Not every TFF process behaves the same way.

A platform selected for monoclonal antibodies may not automatically be the optimal choice for:

  • LNPs
  • mRNA
  • Viral vectors
  • Exosomes
  • Cell therapies
  • Highly shear-sensitive biologics

The growth of advanced modalities means buyers should evaluate performance based on their specific process.

Repligen specifically identifies the KrosFlo portfolio for applications ranging from conventional biologics to newer modalities, including mRNA and gene therapy.

5. Single-Use Strategy

Single-use manufacturing can reduce cleaning requirements and improve flexibility, but buyers need to assess:

  • Consumable availability
  • Supplier capacity
  • Supply-chain redundancy
  • Extractables and leachables requirements
  • Waste generation
  • Cost per batch

The strongest purchasing strategy is not simply asking, “Is this system single-use?”

Instead ask:

Can our organization build a reliable, commercially sustainable supply chain around this platform?

6. Total Cost of Ownership

The equipment purchase price is only one component.

Companies should evaluate:

System cost + consumables + filters + flow paths + validation + installation + training + maintenance + spare parts + software + service + operator time.

Automation can have a higher initial cost but potentially create value through improved process consistency and reduced manual intervention.

The ROI calculation should therefore be linked to actual manufacturing metrics.

7. Supplier Support

For GMP manufacturing, supplier support can directly affect timelines.

Evaluate:

  • Application support
  • Process development expertise
  • Field service availability
  • Validation documentation
  • Training
  • Response times
  • Global service footprint
  • Spare-parts availability

For a global CDMO, supplier service capabilities may be nearly as important as the system itself.

8. Future Product Roadmap

Before selecting a system, ask the supplier:

What comes next?

A platform should be evaluated against its future capabilities, including:

  • AI-assisted process analytics
  • PAT integration
  • Real-time concentration measurement
  • Advanced sensors
  • Digital twins
  • Remote monitoring
  • Automated recipe optimization
  • Predictive maintenance

A platform with a strong roadmap can reduce the risk of technology obsolescence.

Repligen describes its Automatic Back Pressure Valve as proprietary technology for automated TMP control within compatible KrosFlo systems.

However, competitive patent strategy should not be measured simply by counting patents.

A useful patent intelligence program should investigate:

Who is filing → what technologies are being protected → where filings are increasing → which patents are approaching expiration → where white-space opportunities exist.

For equipment manufacturers, this can identify:

  • Freedom-to-operate risks
  • Licensing opportunities
  • Acquisition targets
  • R&D white spaces
  • Emerging competitors

FDA’s Purple Book also provides a useful reminder that biologics competition itself includes significant exclusivity and competitive dynamics, with information on licensed biologics, biosimilars, interchangeability and applicable exclusivity included in the FDA database.
