  • Motionless mixer as cell culture propagator
    Patent number: 4415670
    Abstract: Use of a static mixing system element as a tissue culture propagator. The element comprises an assembly of parallel sheets shaped to provide a plurality of mixing cells wherein fluid entering a cell from two separate inlet channels is rearranged due to shearing and extensional forces and divided into two new outlet streams each of which leaves the mixing cell in a different direction from either inlet stream. The configuration of the device provides uniform flow across all surfaces for precise control of growth conditions and maximum cell growth.
    Type: Grant
