The Jouan B 4i is a non-refrigerated benchtop centrifuge designed for high-speed biological sample separation, featuring:

  • Maximum speed: 14,000 rpm / 18,400 xg, ensuring efficient centrifugation for molecular biology and microbiology applications.
  • Timer range: Adjustable from 30 seconds to 99 minutes plus hold position, providing precise control over centrifugation cycles.
  • Ventilation system: Limits temperature increases inside the rotor chamber to +3°C to +10°C, preserving sample integrity during processing.
  • Safety features: Imbalance detection system that immediately activates the brake to prevent equipment damage and ensure user safety.
  • Included rotor: Swing-bucket rotor S40 with max speed of 4,300 rpm; equipped with four adapters for 5 blood collection tubes (7/10 ml) and four adapters for 50 ml Falcon tubes.
  • Dimensions and weight: 372 x 400 x 495 mm (H x W x D) and 40 kg, making it compact for laboratory benchtops without compromising capacity.

This centrifuge is widely used in molecular diagnostics, bioprocessing, and biotechnology research, particularly for gene editing and synthetic biology workflows requiring reliable sample separation. Its precision control and robust construction make it critical in biopharmaceutical production pipelines and clinical diagnostics involving blood and cellular samples. The Jouan B 4i supports a broad range of applications, including live-cell imaging preparation, fluorescence analysis sample prep, and biomedical engineering research.

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.
