Abstract
A large capacity centrifugal vacuum concentrator includes a rotor assembly mounting a plurality of vertical spaced rotors mounted on a drive shaft and intervened with spacers between each lower rotor and a rotor next above, the rotors and spacers having interengaging drive transmission means for transmitting drive to the rotors and spacers when the drive shaft is driven. The rotor assembly is enclosed by a, e.g., cylindrical stainless steel cover which sits on a base and with the base defines a vacuum chamber. When the cover is elevated to open position, four quadrant access is available for loading and unloading of samples on the rotors. The rotor assembly is made up of interchangeable rotors, spacers and vessel holder frames which are selected from families of such dependent on particular vessel capacity and holder frame requirements.
