Laboratory SFC Systems

Going green has never been so easy

From the food industry to aerogels and polymers and many other industries inbetween, Applied Separations is meeting the growing, world-wide commitment to a cleaner, greener environment.

Environmentally friendly Supercritical Fluid (SCF) technology works with today's innovative, easy-to-use systems.

Unique benefits of supercritical fluid extraction systems


  • Cleaner extraction process with supercritical CO2 compared to conventional extraction solvents
  • No petroleum based solvents required
  • No toxic solvent residues remain in the product, due to the volatility of supercritical CO2
  • No health hazards due to elimination of hazardous and toxic solvents
  • Extracts have longer shelf-life and better blending characteristics due to co-extraction of antioxidants and lipids.
  • CO2 is Safe, inexpensive and readily available
  • CO2 is an ideal substitute for many hazardous and toxic solvents
  • CO2 has good mass transfer, due to the low viscosity of the solvent
  • Supercritical CO2 is a selective solvent based upon its variable density (e.g. extraction of caffeine from green coffee without removal of flavour precursors)
  • Offers solubility without surface tension, supercritical CO2 has the properties of both a liquid and a gas, making even the most sensitive of processes possible
  • CO2 has a low overall energy expenditure
  • Only existing CO2 is used, not produced, in the SCF process
  • NO addition to any greenhouse effect

What is supercritical CO2?


  • Carbon dioxide is in its supercritical fluid state when both the temperature and pressure equal or exceed the critical point of 31°C and 73 atm (see diagram).


  • In its supercritical state, CO2 has both gas-like and liquid-like qualities, and it is this dual characteristic of supercritical fluids that provides the ideal conditions for extracting compounds with a high degree of recovery in a short period of time.


  • By controlling or regulating pressure and temperature, the density, or solvent strength, of supercritical fluids can be altered to simulate organic solvents ranging from chloroform to methylene chloride to hexane.


  • This dissolving power can be applied to purify, extract, fractionate, infuse, and recrystallize a wide array of materials.

Helix - for Process Development


The Helix™ Laboratory Supercritical Process Development Unit is a modular system designed for maximum flexibility and scalability. Depending on your needs, this unit can be configured to handle a multitude of tasks, using only the modules you require for your specific process.


The Helix system also allows for changing process development needs and budgets. All modules can be purchased initially or new modules can be seamlessly added to the unit as development needs change or budgets allow.


The Helix System's scalability and flexibility provides the opportunity to focus on what matters most in the lab-output. Should future needs require a new module, that module will be compatible with the original Helix™ basic system.


Major Helix System features include:

  • Variable temperature control to 240°; pressure to 10,000 PSI/690 BAR
  • Pump: 400 mL/min. flow rate for atmospheric (incompressible) liquid (Available upgrade to 800mL/min). Available in both air and electric drive
  • Extraction vessel assembly sizes: 1000mL, 500mL, 300mL
  • Cyclonic separator vessel assembly sizes: 1000mL, 500mL, 300mL
  • Independent temperature and pressure controls for extraction and separation vessel modules
  • Modifier addition capability
  • CO2 Recycle - An environmentally alternative to releasing CO2 into the atmosphere
  • Stirrer addition capability (optional stirrer assembly) (multiple impeller head options available)
  • 12” x 22” (30.48 cm x 55.88 cm) base unit footprint.


Helix System modules can also be configured to:

  • Subcritical water extraction
  • Use alternate gases in place of CO2
