Patent number: 10271543Abstract: A fluid sample vessel includes inlet and vent tube fittings formed at one end of a container with an opposite open end closed by a needle septum. A support cap is removably engaged to the container to support the container and protect terminal ends of inlet and vent tubular branches coupled to the fittings. The support cap includes a pair of opposite legs with outwardly directed tabs for mounting within a centrifuge while supporting the cryopreservation container.Type: GrantFiled: December 14, 2016Date of Patent: April 30, 2019Assignee: Cook General Biotechnology LLCInventor: Erik John Woods

Patent number: 9877475Abstract: An auto-nucleating device includes a tube containing a crystalline cholesterol matrix. The ends of the tube are closed by a membrane that is impermeable to the cholesterol but permeable to liquids contained in a cryopreservation vessel. The auto-nucleating device provides a site for ice nucleation during freezing of the liquid within the vessel. One such cryopreservation vessel is a flexible vial having a closed port at one adapted to be pierced by a needle to withdraw the liquid within, and an opposite end that is initially open to receive the liquid. Another vessel includes an adaptor mounted to liquid container with a tubular branch closed by a needle septum and another tubular branch provided with a barbed fitting for engaging a flexible tube that terminates in a needle septum. In another embodiment, the vessel includes an inlet and vent branch at the top of the container and an outlet septum at a bottom opening.Type: GrantFiled: January 8, 2015Date of Patent: January 30, 2018Assignee: Cook General Biotechnology LLCInventors: Erik John Woods, John K.

Patent number: 9415146Abstract: 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.Type: GrantFiled: March 15, 2012Date of Patent: August 16, 2016Assignee: Cook General Biotechnology LLCInventor: Alan Robert Brunsman
