NOTE is used to call attention to notable information that should be followed during installation, use, or servicing of this equipment. Safety During Installation and/or Maintenance This ultracentrifuge is designed to be installed by a Beckman Coulter Field Service representative. Installation by anyone other than authorized Beckman Coulter personnel invalidates any warranty covering the ultracentrifuge.
Safety Notice Electrical Safety Electrical Safety To reduce the risk of electrical shock, this equipment uses a three-wire electrical cord and plug to connect the ultracentrifuge to earth-ground. To preserve this safety feature: • Make sure that the matching wall outlet receptacle is properly wired and earth-grounded. Check that the line voltage agrees with the voltage listed on the name-rating plate affixed to the ultracentrifuge.

We recommend that you read this entire manual, especially the...
CFC-Free Centrifugation To ensure minimal environmental impact, no CFCs are used in the manufacture or operation of the Optima MAX-XP Ultracentrifuge. Radio Interference This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of FCC rules.
Figure 1.1 The Optima MAX-XP Ultracentrifuge Intended Use Use the Optima MAX-XP Ultracentrifuge for applications requiring high force fields that are capable of separating and isolating small particles (virus, bacteria, and subcellular components like mitochondria) and large molecules (peptides, DNA, proteins). These samples are derived from a variety of natural and synthesized components.
Description Temperature Sensing and Control Rotor Chamber The steel chamber is coated with a chemical-resistant finish to resist corrosion. The rotor drive hub and speed sensors are visible in the bottom of the chamber. Vacuum System A diffusion pump, in series with a mechanical vacuum pump, reduces chamber pressure to below 10 microns (1.34 Pa).
