Product description

Repligen KrosFlo KR2i TFF system for laboratory tangential flow filtration workflows with integrated software and scales.

The Repligen KrosFlo KR2i Tangential Flow Filtration (TFF) System is engineered for efficient tangential flow filtration processes in laboratory and process development settings. This system integrates:

  • KrosFlo KR2i filtration hardware optimized for precise control of filtration parameters essential in bioprocessing and molecular diagnostics workflows.
  • Peristaltic pump module providing gentle, pulse-free flow, critical for preserving biomolecule integrity in biotechnology applications such as gene editing and synthetic biology research.
  • KFCM software and scales module enabling real-time monitoring and accurate mass balance during filtration, facilitating process development and biopharmaceutical production pipeline optimization.
  • Tubing and stand support assembly for secure fluid handling and system stability, supporting reproducible live-cell processing and bioseparation tasks.

Widely adopted by researchers and scientists engaged in bioprocessing, molecular biology, and biomedical engineering, the KrosFlo KR2i system supports critical tangential flow filtration operations used in protein concentration, buffer exchange, and cell harvesting. Its design ensures compatibility with diverse filtration membranes and scalability from lab bench to pilot processes, making it essential for controlled biomanufacturing and synthetic biology projects.

This technical configuration facilitates essential molecular cloning workflows and comprehensive filtration process control, meeting the stringent demands of biotechnology and clinical diagnostics laboratories.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
