The Beckman Optima MAX ultracentrifuge series are microprocessor-controlled desktop systems that generate high centrifugal force for a variety of high-speed applications. Beckman ultracentrifuges are designed with a variable frequency induction drive and rotor overspeed recognition system. The Optima Max centrifuge or Optima Max personal also has a program memory that can contain up to 10-step programs with selectable acceleration and deceleration rates.
Easy to operate, the high-speed MAX series can be used for a variety of applications including particle membranes, proteins, viruses or DNA, and also to separate DNA or protein density gradients. The Beckman Optima MAX ultracentrifuge operates at 5000 to 130,000 rpm in 1000 rpm increments, while the more economical Beckman Optima MAX-e ultracentrifuge operates at 5000 to 130,000 rpm in 1000 rpm increments. 100,000 rpm operation.
Beckman Optima MAX and MAX-e centrifuges are considered low maintenance systems due to their direct drive induction motors with thermionic air cooling and moisture purification vacuum systems. When placing the rotor in the chamber, the Beckman system automatically secures the drive hub through the self-locking rotor attachment, which is an audible click.
Both the Beckman Optima MAX centrifuge and the Beckman Optima MAX-e centrifuge reduce centrifugation time for applications and allow quick access when placed on a lab bench. The structure of the system also helps avoid long shipping times in favor of more sensitive samples.
