Product description

Used Beckman JA-20 fixed-angle rotor 334831 for centrifuges holding 8×50ml tubes, suitable for bioprocessing and molecular biology applications.

This Beckman JA-20 fixed-angle rotor (model 334831) is designed for centrifugation tasks requiring capacity for 8 tubes of 50 ml each. The rotor is a key centrifuge accessory widely used in biotechnology and molecular diagnostics workflows for efficient sample sedimentation and separation. Optimized for clinical diagnostics, bioprocessing, and synthetic biology, its fixed-angle design ensures consistent centrifugal force distribution for reliable pelleting and fractionation.

Key specifications and features:

  • Type: Fixed-Angle Rotor
  • Capacity: 8 × 50 ml tubes
  • Model Number: 334831
  • Manufacturer: Beckman
  • Compatible with various Beckman centrifuge models supporting JA-20 rotors.
  • Ideal for cell culture processing, gene editing sample prep, and biomanufacturing quality control.

As this item is sold used, it is provided as-is, with no guarantee of performance equivalent to new conditions. It is important for researchers and lab technicians to verify functionality before critical applications. This rotor supports many centrifugation protocols in molecular biology and clinical research labs, making it a robust option in secondary markets.

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.
