The company has 30 years experience in SCF technologies and offers a wide range of systems, from laboratory instruments to pilot plants to large scale production facilities.

Now 25 years in business, Norlab is a specialist supplier of Separation Science & Dissolution Instruments and Accessories, Laboratory Fluid Handling Solutions and more...
To celebrate our 25th anniversary, we are planning special deals and promotions throughout the year. We encourage you to stay informed by signing up for our newsletter.

The Applied Separations Spe-ed supercritical fluid (SCF) product line features:

  • Educational systems
  • Laboratory systems
  • Pilot scale process systems
  • Large scale production systems

Spe-ed Helix laboratory supercritical fluid process development systems
The Helix has been specially engineered by Applied Separations for maximum flexibility. The modular Helix is optimized, so the system can easily be modified for changing process development needs.

Applied Separations Spe-ed SFE-2 and Spe-ed SFE-4 analytical and research systems
The Spe-ed SFE-2 and the Spe-ed SFE-4 are, respectively, 2-vessel and  4-vessel simultaneous oven-based extraction systems.

Applied Separations Spe-ed SFE-15000 higher pressure oven-based extraction system
The system has been designed with special high pressure components to reliably provide rugged service, and increased solubility of many compounds.

Spe-ed SFE-Prime for supercritical fluids education
Spe-ed SFE-Prime is the only teaching tool for environmentally friendly supercritical fluids technologies.

Large scale SFE systems
Applied Separations offers custom pilot plant/small production and large scale production SFE systems.

Supercritical Fluid Extraction (SFE)
SFE uses supercritical CO2, instead of organic solvents such as hexane and methylene chloride, to extract chemical compounds from a solid matrix (sometimes also from liquids). Near the critical point the density of a SCF is extremely sensitive to minor changes in temperature and pressure. Since the solvating power of a SCF is directly related to its density, selective extraction of the analyte of interest can be achieved by making slight changes in temperature and pressure and exploiting the differential solubility of analytes in the SCF. On the other hand, due to the higher diffusion coefficients in supercritical fluids, SFE is faster than liquid extraction. SFE is also a more efficient extraction method since the lower surface tension of supercritical fluids allows penetration into small pores of the solid matrix which are not accessible to liquids.
