Toll Processing & Custom Manufacturing

Versatile and Scalable

The toll processing facilities at Phasex are the most versatile in the U.S. We have four operational suites. Each suite has two vessels; the size of each vessel in the suites range from 200 to 400 liters. 

  • Pending capacity additions—2 suites: one in 2022; one in 2023


Manufacturing campaigns are carried out for many markets and applications:

Natural Products

  • Herbs
  • Nutraceutical ingredients
  • Dietary supplements
  • Organic products  (hemp & cranberry)
  • Hemp & CBD


  • Medical polymers
  • Polymeric fibers used in pharma applications


  • Lubricants
  • Reactive monomers
  • Specialty chemicals
  • Surfactants
  • Reclamation of recycled plastics -> clear-like virgin material

Our ability to process from 1,000 or 10,000 kg quantities—to 100,000 kg quantities—enables our customers to evaluate supercritical fluids for their specific needs without investing early stage and high-risk capital. Our expertise ensures rapid development and scale, minimizing your costs and decreasing your time-to-market.

Since our founding in 1981, our goals have remained unchanged: to apply supercritical fluids to the development of innovative, industrially-viable separation processes for extracting, purifying, recrystallizing, and fractionating a wide range of polymers, natural materials, and specialty and fine chemicals.

Phasex is staffed by a team of problem-solving chemical engineers, chemists, and technical specialists. We provide a complete range of supercritical fluid extraction services: feasibility studies, research and process development, toll processing, and technology licensing.
