The Beckman Coulter MLS 50 is a high-speed swinging-bucket rotor designed for Beckman Coulter Optima MAX and MAX-E ultracentrifuges. It supports small-volume sample separation at speeds up to 50,000 rpm and a maximum relative centrifugal force of approximately 302,000 × g.

  • Rotor type: Swinging bucket
  • Maximum speed: 50,000 rpm
  • Maximum RCF: Approximately 302,000 × g
  • Capacity: 4 × 5 mL
  • Tube compatibility: Thinwall or Thickwall tubes, depending on model
  • Compatible instruments: Beckman Coulter Optima MAX and MAX-E ultracentrifuges
  • Material: High-strength anodized aluminum
  • Weight: Approximately 1.5 kg
  • Temperature compatibility: Suitable for refrigerated applications
  • Lid: Screw lid with safety lock

The swinging-bucket configuration positions tubes horizontally during centrifugation, supporting sharp fractionation and reproducible separation. This ultracentrifuge rotor is suitable for molecular biology, biochemistry, cell biology, biotechnology, and small-volume sample preparation workflows, including applications in molecular diagnostics and biopharmaceutical research.

Included components are four 43.9 g cups/hangers, cover gasket 975001, and cup seal 824412. The rotor is described as very rarely used and in like-new condition, with no visible damage, corrosion, or imbalance. It has been fully tested and is ready for use.

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.
