The Beckman Allegra 64R centrifuge is a brushless, induction drive refrigerated centrifuge which performs routine spins on the lab bench. This centrifuge has a speed of 64,000g (30,000rpm) with a fixed-angle rotor (not included) and has a capacity for samples from 250uL to 85mL. The Beckman has a programmable temperature from 2 to 40C. The Allegra is ideal for high-speed separations, including cell gradient spins, nucleic acid precipitations, DNA mini-preps, protein precipitations, phase extractions, spin columns and subcellular fraction pelleting. The centrifuge's easy-to-use control panel displays actual speed, RCF, time, temperature, and acceleration/deceleration rates. It can be customized for routine runs with multiple acceleration/deceleration profiles. Safety features include a door interlock that prevents contact with spinning rotor and over-temperature/over-speed diagnostics that protect samples. Uses CFC-free refrigerant. The quiet (65dB), brushless induction drive motor can be set in 100rpm increments and is accurate to +/-50rpm. A flexible drive shaft helps compensate for drive imbalances. The Beckman 64R centrifuge accommodates a selection of 13 rotors (may be ordered new from manufacturer). See the attachment for the rotors that are available from VWR:
