Features
The Allegra 6R features Beckman’s Automatic Rotor Imbalance Equilibrium System (ARIES) and can automatically identify and correct rotor imbalance of up to 50g. Depending on rotor selection, the Beckman Allegra 6R can swing a wide variety of tubes, bottles, plates, and blood bags. This centrifuge features a simple user interface with analog controls with a digital display.
Testing
This Beckman Allegra 6R Refrigerated Benchtop Centrifuge used and reconditioned. Our expert technicians meticulously test every centrifuge to ensure optimal performance and reliability, leaving no detail overlooked. They thoroughly balance the rotating assembly, inspect the bearings, seals, and gaskets, and confirm the proper functioning of all controls.
For refrigerated centrifuges, they verify the unit reaches and maintains the desired temperature accurately. All tolerances are carefully measured, and both the interior and exterior are fully cleaned for a polished finish. When sold with a rotor, technicians test the rotor and centrifuge combination together for seamless operation.
Rotors undergo a rigorous inspection process, including buckets, gaskets, and overspeed disks. Fixed-angle rotors are assessed for body integrity, while swinging bucket rotors are checked for proper weight distribution. Whenever possible, each rotor is run in a compatible centrifuge to confirm flawless performance, ensuring you receive equipment that meets the highest standards.

Beckman Allegra 6R Centrifuge – Frequently Asked Questions
What is the Beckman Allegra 6R centrifuge?
The Beckman Allegra 6R centrifuge is a refrigerated benchtop centrifuge designed for clinical labs, research facilities, and general sample processing. It delivers reliable centrifugal force for applications such as cell separation, protein precipitation, and blood processing.
What applications is the Allegra 6R best suited for?
The Allegra 6R is highly versatile and commonly used for blood and urine sample processing, cell pelleting and microbial separation, protein and nucleic acid preparation, clinical diagnostics and teaching labs, multiwell plate and high-throughput sample workflows. Its large capacity and flexible rotor options make it ideal for both routine and research applications.
What are the key features of the Beckman Allegra 6R?
Key features include:
- Refrigerated operation for temperature-sensitive samples
- Maximum speeds up to ~8000 rpm (depending on rotor selection)
- Temperature range: approximately -10°C to +40°C
- Large capacity (up to ~3 liters depending on rotor)
These features ensure consistent, repeatable performance in demanding lab environments.
What types of rotors and tubes are compatible?
The Allegra 6R supports a wide range of rotors, including:
- Swinging-bucket rotors (e.g., blood tubes, bottles, plates)
- Fixed-angle rotors for faster pelleting
- Capacity for tubes ranging from 1.5 mL microtubes to 750 mL bottles
This flexibility allows labs to run multiple protocols on a single instrument.
What is included with a refurbished Allegra 6R from American Instrument Exchange?

Upgrading from the Beckman Allegra 6R
When should I consider upgrading from the Beckman Allegra 6R?
Many labs continue to rely on the Allegra 6R for years, but upgrading may make sense if you need:
- Higher maximum speed or g-force
- Improved temperature stability and faster cooling
- Quieter operation and better ergonomics
- Expanded rotor compatibility or automation features
If your workflows are evolving (higher throughput, new sample types, or regulatory requirements), a newer centrifuge can improve efficiency and consistency.
What are popular upgrade options to the Allegra 6R?
Common modern replacements include:
- Eppendorf 5810R centrifuge
- Beckman Allegra V-15R centrifuge
- Thermo Scientific Megafuge ST4R Plus centrifuge
