If the “Dynamic Dialysis” I’m thinking of is the same one you heard about at the conference, then it is actually a combination product and process. The trade name is SpectraFlo and it is available from Repligen. The leading feature of this solution is the utilization of fluidic dynamics to increase purification efficiency. It is this latter portion that makes me think this is the system you heard about. I have included a link below to more information.
