PowerSpin Centrifuges

United Products & Instruments PowerSpin Centrifuges have a compact, space-saving footprint and many features typically found only in more expensive units. A brushless motor runs at a quiet 58 dB, even at the maximum 3400 rpm. The 30-minute rotary timer has a bell to signal the run's end. Suction cup feet keep the unit stable on the benchtop.

Each centrifuge includes a durable, polymer 6-place angle rotor that will accommodate most tubes up to 16 x 110 mm in size. A safety interlock prevents units from operating when the lid is open. The rotor is removable to access the stainless centrifuge chamber. A lid window can be used for manually checking RPM via a tachometer (not included). 

Centrifuge EF4335A is a 3400 RPM fixed speed unit. 

Centrifuge EF4335B has variable speed between 300 and 4000 RPM. 

Both centrifuges include a detachable power cord, power light indicator and one year limited warranty. The optional 8-place rotor is available for applications that require increased capacity.

Key Features

  • Extremely quiet for a better working environment
  • Removable rotor makes cleaning chamber easy
  • One-year warranty
