Beckman Allegra X-12R Refrigerated Benchtop Centrifuge

With reliable temperature control, the Beckman Allegra X-12R Refrigerated Benchtop Centrifuge is ideal for cellular research including such applications as general separation and cell harvesting. The microprocessor control display allows you to select from 20 user-defined programs, 10 independent acceleration profiles, time options, and to set up your run by rpm and RCF prompts.

Beckman Allegra X-12R features

The Allegra X-12R centrifuge uses CFC-free refrigerant and allows a selection of temperature within the range of -10°C to 40°C. It holds temperatures for up to 10 minutes after a run has stopped.

Specifications

Temperature range: -10°C to 40°C
Automatic initial soft start
Automatic rotor identification
Brushless induction drive
90-day warranty

Features

This unit includes the SX4750A ARIES self-balancing swinging bucket rotor, which automatically corrects imbalance in opposing loads up to 50 g and continues to run without shutdown.

Centrifuges also accommodate cell culture flask adapters to allow the direct centrifugation of cell culture flasks, which eliminates the transfer step to and from conical tubes for cell separation. This not only saves time and labor but also reduces the chance of contamination.

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.

We also test refrigerations to make sure that the machine reaches and hold temperature properly. We measure all tolerances and clean the exterior and interior of all units. If the unit is being purchased with a rotor, we test the rotor/centrifuge combination together.

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
