1900s. The next major step forward in the evolution of the centrifuge came during the 1920s and 1930s, when the ultracentrifuge capable of achieving 900,000 gwas developed by the Swedish colloid chemist Theodor Svedberg. Models capable of reaching 900,000 g tended to have small rotors, so ultracentrifuges with larger rotors that could operate ...

Thermal characteristics of the limonite laterite ore types have been studied using TG / DTA. There are four endothermic peaks at 250, 646, 900, and 1023 °C with a total mass loss of 10.07wt%. These four peaks correspond to the XRD results on samples calcined at 600-1000 °C. Analysis of TG / DTA to the mixture of limonite and graphite …
If a spill occurs, clean the rotor and buckets immediately. 9. Wipe down the rotor and centrifuge after each use. To keep the centrifuge clean and running smoothly, lightly clean the rotor and wipe down the centrifuge at the end of a run. When you are finished, leave the lid open so it can air out and remain dry.

The answer is easier than you think…. The force exerted on a particle in a centrifuge is a simple function of the rotation speed of the centrifuge and the radius of rotation. The actual equation is: RCF or G-force= 1.12 x R x (RPM/1000)². R is the radius of rotation measured in millimetres. For example in the photograph below R is 240mm.
