Product description

KR2i pump for precise fluid circulation in protein purification and cell culture concentration workflows.

The Spectrum Labs KrosFlo TFF Tangential Flow Filtration System KR2i Pump is designed for tangential flow filtration (TFF) applications involving the separation and concentration of proteins, cell cultures, and other biopharmaceutical samples.

The KR2i pump provides uniform fluid circulation for efficient membrane filtration and concentration in biotechnology, bioprocessing, pharmaceutical production, and biological product manufacturing workflows. It is compatible with KrosFlo TFF membranes and system components and integrates with existing KrosFlo tangential flow filtration setups.

Key applications:

  • Protein purification and concentration
  • Cell culture concentration
  • Biopharmaceutical sample processing
  • Biological product manufacturing
  • Biotechnology and pharmaceutical filtration workflows

Technical specifications:

  • Function: Optimized pump for uniform fluid circulation during TFF processes
  • Flow: High flow rates for efficient sample filtration and concentration; exact flow rate not specified
  • Material: Corrosion-resistant construction for chemical and biological environments
  • Connection: Designed for integration with KrosFlo TFF components
  • Design: Compact, robust construction for laboratory environments
  • Dimensions: Approximately 350 mm × 500 mm × 250 mm (W × D × H)
  • Weight: Approximately 15 kg
  • Accessories: Components for integration into existing TFF systems are included according to the listing

This laboratory tangential flow filtration pump is suitable for researchers and bioprocessing professionals performing protein purification, cell culture processing, and other molecular biology or biopharmaceutical concentration procedures.

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.
