Abstract: A system including a fluid receiver defined by a crystallization chamber, three or more fluid input conduits, wherein each fluid input conduit is configured to direct a fluid into the crystallization chamber such that the fluids from the fluid input conduits converge on a single spatial coordinate (X—Y—Z) within the crystallization chamber, and a fluid outlet body portion. A process for crystallization of the chemical compound is also disclosed. Polymorphs of paracetamol, carbamazapine, ketoprofen, atorvastatin, and itraconazole also are disclosed.
