NuAire offers the Hitachi himac CS150NX tabletop micro ultracentrifuge—a compact device that saves laboratory space and is suitable for use with proteins, lipoproteins, cell organelle, DNA, RNA, viruses, carbon nanotubes, and nanoparticles. Protocol information is entered via a touch-sensitive LCD with graphic user interface icons. In addition, the ultracentrifuge has a quiet operation of 45 dBA, takes only 90 seconds to reach 150,000 rpm (a RCF of 1,050,000 x g), and has a non-contact imbalance sensor that monitors the vibration of the rotor and drive shaft. In the event of abnormal vibration, the sensor stops the operation immediately. Users can install and remove rotors by simply placing them on the drive shaft, and the rotor is automatically locked by centrifugal force.
