The Beckman Allegra 21R benchtop centrifuge is microprocessor controlled with a brushless three-phase drive system, automatic rotor overspeed ID system, program memory, and a choice of acceleration and deceleration rates. The Beckman Allegra 21R also includes safety features like a dual electromechanical locking mechanism to prevent contact with spinning rotors and a steel barrier surrounding the rotor chamber. The Allegra 21R can be used for a variety of applications including processing sample preparations, pelleting, extractions, purifications, concentrations, phase separations, receptor binding, and column centrifugations, as well as processing large numbers of small volume samples in multiwell plates for tissue-culture cell concentration.

All 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. 

Our technicians inspect all rotors, including any buckets, gaskets and overspeed disks. Fixed angle rotors are closely inspected for body integrity; swinging bucket rotors supplied with buckets are checked for proper weight distribution. When possible we run each rotor in a compatible centrifuge to make sure the rotor spins properly.

The photos are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that 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 it has been tested and cleaned.
