Below is a list of Gas Centrifuge manufacturers from Des Moines, Iowa. Gas centrifuges are highly specialized devices used for the separation of isotopes in gaseous materials and mixtures. Like all centrifuges, the basic operation involves the input of materials that are then rotated at high speeds. The resulting centrifugal force allows for the separation of molecules based on mass. Most centrifuge models are capable of sorting and separating gaseous materials, but are more frequently used to separate solids from liquid suspensions.
