An effortless operation was the primary goal when developing the user interface of Centrifuge 5910 Ri. Setting new parameters can now be done in seconds via the favorites function. Up to 99 frequently-used programs are directly accessible on the home screen.
Your samples are valuable, which is why the temperature management system of Centrifuge 5910 Ri goes beyond just cooling. It offers rapid pre-cooling and patented Dynamic Compressor Control (DCC) technology to maintain a steady temperature throughout the run. Additional safety features such as automatic rotor recognition, built-in imbalance sensors and a motor-driven lid lock ensure your peace of mind.
The Eppendorf 5910Ri makes documenting your runs easier than ever. You can track user access and digitally document all runs – including parameters such as time, temperature, ramps, and other events; manage your data and protect your samples with 3 levels of password-protected user access; and easily transport your data in a PDF or CSV file using the front-mounted USB port and import into digital lab software such as eLABJournal.

Testing
Most of our equipment is used and reconditioned. Our technicians test the performance of all centrifuges and make sure the rotating assembly is properly balanced; the bearings, seals and gaskets on the spindle assembly are in good shape; and the controls work properly.
If the centrifuge is refrigerated, we also test to make sure that the machine reaches and hold temperature properly. All tolerances are measured and the exterior and interior of all units are fully cleaned. If the unit is being purchased with a rotor, we test the rotor/centrifuge combination together.
Pictures
The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse. In addition to testing each machine we will clean all the equipment thoroughly prior to shipment.
We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after testing and cleaning.

Eppendorf 5910Ri centrifuge FAQs
Do you provide bucket inserts with the rotor?
We sometimes have insert for the S-4x rotor available to sell with a centrifuge and rotor combination. Because of the volume of equipment we are currently receiving in stock we are not able to list all inserts separately. Please call or email our sales team for information if you require inserts along with your purchase of an Eppendorf 5910RI.
Do you offer repairs for Eppendorf centrifuges?
Yes, we can repair most Eppendorf centrifuges including the 5910RI. Depending on your location and the nature of the malfunction we can provide either field service or depot repair. Find our more about lab equipment repair options here.
Do you offer white glove delivery service for the Eppendorf 5910RI?
For customers in the United States our carriers can provide freight shipping, unpacking, and inside delivery of most equipment, including setting the equipment in place in your lab. For customers in Greater Boston and New England we can send one of our technicians to make sure the centrifuge is properly balanced and provide basic instructions and training for your laboratory personnel after delivery.
Why is the S-4x called a universal rotor?
Because of the wide range of applications and tube sizes it accommodates. The S-4x can spin anything from 5mL tubes to 1L Nalgene bottles. We can provide manuals to customers with more information upon request.
Testing Procedures for Used and Refurbished Laboratory Centrifuges
Ensure Quality, Accuracy, and Compliance Before Deployment
Used and refurbished laboratory centrifuges from American Instrument Exchange undergo testing procedures to ensure they meet the performance, safety, and compliance standards required in modern laboratories.
Why Testing Used Laboratory Centrifuges Is Essential
Before a centrifuge is reintroduced into a lab environment, it must be tested for:
Mechanical integrity
Rotor balance and speed accuracy
Safety system functionality
Electrical compliance
Proper testing helps extend equipment lifespan, reduce downtime, and ensure safety in high-stakes lab environments such as clinical diagnostics, biotechnology, and research applications.
Our structured testing protocol for used and refurbished centrifuges ensures equipment safety, accuracy, and longevity.
Key Testing Procedures for Refurbished and Used Centrifuges
1. Initial Visual Inspection
Check for signs of wear, corrosion, or damage to housing, lid, and control panels
Inspect power cords, plugs, and connectors for fraying or exposed wiring
Confirm that the rotor and accessories are compatible and undamaged
2. Functional Testing
Power up the centrifuge and confirm successful boot-up of digital or analog displays
Test lid lock and emergency stop mechanisms
Run initial cycles at various speeds to check for abnormal noise or vibration
3. Rotor and Speed Verification
Test all programmable speed settings to confirm consistent acceleration and deceleration
Monitor temperature, vibration, and RPM consistency throughout the cycle
Balance testing ensures smooth operation and prevents wear on internal components
4. Electrical Safety and Grounding Tests
Verify that all electrical components are properly grounded and shielded
5. Temperature Control (if applicable)
For refrigerated centrifuges, test cooling function to ensure temperature stability within set ranges
Check refrigerant levels and inspect for compressor noise or failure
6. Final Quality Assurance Checklist
Conduct a full run-through using the user interface
Document all test results
