Fullerton, Calif. (September 5, 2007) – Beckman Coulter, Inc. introduces the Optima™ MAX-XP benchtop ultracentrifuge. The next generation in the company’s successful Optima line, the new instrument delivers fast run times of up to 150,000 RPM (2,500 revolutions per second) and is exceptionally quiet – producing only half the sound power of other benchtop models. A new MLA-150 fixed-angle rotor for the Optima MAX-XP has a low k-factor for rapid separation of small volume samples such as subcellular particles, viruses and proteins.
