The B4i and C3i multifunction centrifuges are available in ventilated and refrigerated versions. Ideal for clinical biology, these centrifuges have a high capacity swing-out rotor (4 x 290 mL);, are equipped with a quiet, brushless induction motor; and operate at up to 14,000 rpm with a relative centrifugal force of 18,407 x g. The patented Auto-Lock rapid rotor exchange system makes the B4i and C3i multifunction centrifuges truly versatile by minimizing set up time – rotors can be exchanged in less than five seconds
