  • Applications: Liquid chromatography, FPLC, HPLC, and protein purification
  • Compatibility: GE ÄKTA Explorer, Pure, Prime, and related systems
  • Maximum pressure: Up to 6 MPa (60 bar), depending on system configuration
  • Typical flow range: 0.1–10 mL/min, depending on the model and system setup
  • Materials: Stainless steel and PEEK
  • Connection thread: UNF 10-32, standard FPLC connection
  • Dimensions: Approximately 30 mm × 6 mm (L × diameter)
  • Weight: Approximately 15 g

The compact FR-904 design supports straightforward integration into existing chromatography setups. It is suitable for sensitive separation workflows where controlled backpressure helps protect chromatography columns and samples, including biotechnology, molecular biology, and biopharmaceutical protein purification applications. The listed component is in very good condition, with no visible external damage or deposits, and is suitable as a replacement or expansion part.

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?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
