Fixed Angle Centrifuge Rotors. Fixed-angle rotors feature a medium pathlength, a fast run time and excellent resolution. In fixed-angle rotors, tubes are held at a constant angle during the spinning operation, typically between 23 – 38 from vertical. They’re commonly used at higher speeds, for small to large volumes, for pelleting applications, such as bacteria and yeast to …

Nov 03, 2020 Centrifugation speed is often given in rotations per minute (rpm), or how many times the rotor completes a full rotation in one minute. Speed can also be given in relative centrifugal force (RCF) or the G-force on the rotor. Modern day centrifuges are digital and have settings for both.

The conversion factor between RPM and g depends on the radius of the centrifuge rotor. The particles' settling velocity in centrifugation is a function of their size and shape, centrifugal acceleration, the volume fraction of solids present, the density difference between the particle and the liquid, and the viscosity .

The disc stack centrifuge is a versatile device, which may be used for separating solid/liquid mixtures in continuous, semi-continuous and batch configurations (see Figures 1.12 and 1.13).All except some batch-operated machines are able to handle toxic, flammable and volatile feeds at throughputs up to 200 m 3 h −1. Liquid-liquid mixtures can be separated and with more …

The Zippe-type centrifuge is a gas centrifuge designed to enrich the rare fissile isotope uranium-235 (235 U) from the mixture of isotopes found in naturally occurring uranium compounds. The isotopic separation is based on the slight difference in mass of the isotopes. The Zippe design was originally developed in the Soviet Union by a team led by 60 Austrian and …
