HITACHI CR-GII Series High Speed Refrigerated Centrifuges

HITACHI CR-GII Series High Speed Refrigerated Centrifuges

High efficiency, too. From the high-torque brushless motor and powerful refrigeration to automatic rotor identification and other time-saving automated functions, these relatively compact units deliver. Optional high-capacity lightweight rotors are easier to transport and load, and they reduce acceleration and deceleration times beyond those achieved by the powerful motor alone.
