Abstract
A particle separator is provided for collection and manipulation of target particles, e.g., target cells, in a closed sterile field condition. In one embodiment, closed sterile field conditions are maintained from separation through concentration and/or cryo treatment steps and/or transfusion. Preservation of closed sterile field condition are accommodated by using the same integrally coupled rigid-walled vessel for collection and concentration and transfer via integrally coupled conduits to a vessel for cryopreservation and/or transfusion. In one embodiment, a plurality of valves are responsive to a data processor for controlling the path of fluid flow through the particle separator. A plurality of sensors are provided for providing sensor signals indicative of fluid flowing through the cell separator. A peristaltic pump is responsive to the microprocessor assembly for controlling the speed and direction of fluid flow through the system. A stir plate assembly is responsive to a signal from the data processor for controllably agitating the contents of the cell separator.
