The CPS Disc Centrifuges are an excellent tool for particle size analysis of virtually any material between 5 nm and 75 µm. The instruments measure particle size distributions using sedimentation, a well known and reliable method of particle size analysis. The CPS Disc Centrifuges operate at up to 24,000 RPM. Many analyses that are impractically long (several hours or more) on competitive sedimentation instruments can be completed rapidly using the CPS Disc Centrifuges.
