  • Rotors sold separately; call for info on available models
  • 90 day warranty

The Beckman J2-21 series centrifuges are built for constant day-to-day use with rugged and reliable construction. An automatic vacuum system reduces windage and provides fast rotor acceleration, accurate temperature control, faster rotor cooling, and long motor life. The Beckman J2-21M features a high torque brushless induction drive for less maintenance and longer life span. The Beckman J2-21 M features microprocessor control with programmable memory that stores 10 programs and eliminates errors in repetitive runs, along with a choice of three acceleration profiles. A rotor identification system provides overspeed protection and automatic temperature compensation for rotor windage. A digital display shows users current rpm and other status information in real time during runs.

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 above 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.
