Phasex, based in Lawrence, MA, was founded in 1981 and is one of early pioneers in application of supercritical fluid technologies. Phasex provides a range of services: Contract R&D, Toll Processing, Technology Licensing and Purified Products. The company has pioneered the application of supercritical fluids in several current operating industrial processes, e.g., fractionation of polymers and lubricants for enhanced viscosity performance, processing of reactive monomers and heat labile surfactants to purity levels not achievable with vacuum distillation or wiped film evaporation, recrystallization of pharmaceuticals and biomaterials with uniformity of particle size not obtained with mechanical or jet milling, and extraction/ separation of pharmaceutical, food, and natural extract products that are free of solvent residues.
