The fixed-angle rotors are capable of spinning 50, 15, 5, and 1.5 mL conical tubes, as well as and 50, 15 and 10 mL round-bottom tubes and bottles. JA-14.50 rotors can deliver a top speed of 14,000 rpm and rcf of 35,000 × g while holding up to 16 × 50 mL conical tubes. Like other Avanti rotors, the new JA-14.50 rotors have a unique ID that can be tracked using magnetic sensors. The Avanti centrifuge/rotor system can ensure that no individual rotor exceeds the maximum speed permitted.
