  • System and method for removing a cryporotectant from a liquid
    Patent number: 9415146
    Abstract: A system for removing cryoprotectant from a cryoprotectant-containing liquid stored a container comprises a cryoprotectant removal device that receives the cryoprotectant-containing liquid and a cryoprotectant-free dialysate liquid and that is operable to transfer cryoprotectant to the dialysate liquid. A differential conductivity device is arranged to continuously measure the difference in conductivity between dialysate liquid entering the device and dialysate liquid that has received cryoprotectant transferred by the dialyzer discharged from the device. A controller is operable to control the flow of the liquids through the device in response to the measured difference in conductivity, and particularly to stop the flow of the cryoprotectant-containing liquid when the measured differential conductivity indicates that the cryoprotectant has been substantially removed from the liquid.
