Abstract
A device for homogenizing a liquid containing a mixture of single cells and cell clusters is provided. The device includes a shroud for channeling the liquid and suspended particles. The shroud defines an inner bore that is formed to include an axial inlet opening and at least one spaced apart outlet opening. A homogenizing bit is provided that is disposed within the inner bore for dispersing the suspended particles in the liquid to form a homogenized substance. The bit includes a shear blade fixed to the bit at a location near the axial inlet opening, with the shear blade configured to cooperate with adjacent shear ports to shear a portion of the suspended particles. The bit also includes a spiral portion that is configured to draw the liquid and suspended particles axially into and through the inner bore from the inlet opening.
