These are disposable ultrafiltration devices used in laboratories for the concentration and purification of biological solutions, such as proteins, antibodies, and nucleic acids. They are designed to fit into standard centrifuges, using centrifugal force to drive liquid through a specialized membrane while retaining larger molecules.
