The SFT-110 Supercritical Fluid Extractor (SFE) was developed for people who want to investigate the feasibility of applying supercritical fluid techniques to a wide variety of analytical and processing problems.

Ideal for use in a variety of applications and settings:

  • High-level precision capable of handling serious research
  • A great tool for teaching laboratories
  • Perfect for natural product extraction, including foods and nutraceuticals
  • Numerous industrial uses, including drying, textile dyeing, parts cleaning
  • Polymer applications
  • Process development and scale-up

A research grade system designed to exacting specifications that provides highly accurate, repeatable results, the SFT-110 is capable of extracting very low levels of key components from materials and processing larger amounts of bulk material than would be possible with smaller, analytical scale equipment. Built with precision, durability, versatility, and safety in mind, the SFT-110 possesses many features typically found in more costly systems, and achieves superior results.

  • Easy to use PID controllers ensure precise temperature and pressure control
  • Integrated Fluid Preheater and Flow Meter for optimal process control
  • Variable restrictor valve for precise flow control
  • High performance, Dual Piston Pump delivers CO2 at consistent rates
  • Built-in safety features to protect against over-temperature or overpressure conditions
  • Accommodates a variety of extraction and collection vessels for maximum versatility
  • Optional Co-solvent Addition Modules
