Abstract:
A system for separating particles, comprising in combination:a fluid chamber includinga fluid chamber inlet,a fluid chamber outlet, anda fluid chamber wall extending between and defining the fluid chamber inlet and the fluid chamber outlet, the fluid chamber wall having an inner surface defining an interior having a maximum cross-sectional area at a position between the fluid chamber inlet and the fluid chamber outlet, the interior converging from the position of the maximum cross-sectional area toward the fluid chamber inlet and converging from the position of the maximum cross-sectional area toward the fluid chamber outlet;inflow tubing coupled to the fluid chamber inlet;outflow tubing coupled to the fluid chamber outlet;a container containing a binding substance including first particles and ligands attached to the first particles, at least some of the ligands being capable of binding with second particles to form groups of bound particles capable of being separated from third particles in the fluid chamber; anda separation vessel having a collection well for retaining particles therein, the separation vessel including a vessel inlet, a particle concentrate outlet for removing at least the particles from the collection well, and a liquid outlet for removing at least liquid from the separation vessel, the vessel inlet being flow connected to the fluid chamber outlet.
