With air-craft grade, premium alloy construction, the 4 x 500ml Swing Bucket Rotor can withstand centrifugal forces upwards of 4,211 x g. Advanced microprocessor controls allow for instant rotor identification, which automatically converts the rotational speed to the relevant g-force (RCF), preventing the user from setting a speed above the capabilities of the installed rotor. In addition to retrieving saved programs, the easy-to-use front panel can adjust acceleration and deceleration rates and change the end of run alarm tone. Rotor exchange is simple and requires less than one minute. As soon as the rotor is placed on the motor shaft, the identification process activates and the installed rotor code is displayed on the backlit LCD display. \n\t\u003cb\u003eThe included 221.08 V04 Swing Bucket Rotor reaches a maximum speed of 4,500 RPM and a maximum RCF of 4,211 x g.\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003eAll of our equipment is in excellent condition and will be fully tested to perform at factory specifications before being shipped.\n\t\u003cbr\u003e\u003cbr\u003ePlease confirm this rotor meets your application needs and request a different rotor, if necessary.
