A variety of scientists and technicians in a number of disciplines (in- cluding chemistry, biology, biomedicine, and molecular genetics) use centrifuges in their laboratories to separate substances of different densities, to remove moisture, and to simulate the effects of gravity. Beckman Instruments Inc., of Fullerton, Calif., has introduced two new series of ultracentrifuges the L and XL Optima series. Both series feature an advanced, 10-year warranted drive that is stress and imbalance-resistant. This eliminates the need for accurately weighing individual systems before they are loaded into the unit. Both models also feature a built-in w^2 t integrator, which displays the total centrifugal effect of a run in radians squared per second, including deceleration time. In addition, the temperature control systems of both series of ultracentrifuges use no chlorofluorocarbons. The air-cooled drive requires no liquid coolants, and the thermoelectric heating/cooling system provides an operating range of 0°°C to 40°C, without a ...
