Ультрацентрифуга Beckman Optima MAX

Product Description Microprocessor control High torque direct drive induction motor Very smooth acceleration/deceleration profiles for gentle sample handling Ultra high run-to-run reproducibility Imbalance tolerant drive means eye balancing of your sample tubes Fast instrument set-up GMI Offers Installation & Training From Our World-Class Beckman Trained Engineers Full Proof of Performance Certification Included GMI Certified Pre-Owned (Eligible for a 1-Year Warranty) The Beckman Optima MAX Ultracentrifuge Series is microprocessor-controlled tabletop systems that generate high centrifugal forces for a variety of high-speed applications. The Beckman ultracentrifuge design features a variable-frequency induction drive and rotor overspeed identifcation system. The Optima Max centrifuge or Optima Max Personal also has a program memory that can contain up to ten-step programs, and offers a choice of acceleration and deceleration rates. Easy to operate, the high-speed MAX Series can be employed for a variety of applications, including pelleting membranes, proteins, viruses or DNA and also separation of DNA or proteins on density gradients. The Beckman Optima MAX Ultracentrifuge runs at 5,000 to 130,000 rpm in 1,000-rpm increments, while the more economical Beckman Optima MAX-E ultracentrifuge operates at 5,000 to 100,000 rpm in 1,000-rpm increments. Due to their direct drive induction motor with thermoelectronic air-cooling and moisture purging vacuum system, the Beckman Optima MAX and MAX-E centrifuges are considered to be low maintenance systems. When placing the rotor in the chamber, the Beckman systems are automatically secured to the drive hub through the self-locking rotor attachment, which is audible by a click sound. Both the Beckman Optima MAX centrifuge and the Beckman Optima MAX-E centrifuge cut down the centrifugation time of applications and allow quick access when placed on a laboratory bench. The structure of the system also helps avoid longer transportation time for the benefit of more sensitive samples.
