Below is a list of Used Centrifuge manufacturers from St. Croix Falls, Wisconsin. Used centrifuges are refurbished devices designed for the separation of particles and isotopes, sedimentation and suspension isolation of materials and objects based on mass, specific gravity, size, shape or density. High acceleration capable of generating centrifugal forces as great as twenty thousand times that of normal gravity causes particles to separate out in a radial direction based on the aforementioned features until a layered sedimentation is produced for reclamation or observation.
