Supercritical Fluid Extraction and Processing System

Supercritical Fluid Technologies, Inc. (USA) introduces a new generation of the SFT-150 Supercritical Fluid Extraction (SFE) System. Developed to investigate the application of supercritical fluid techniques to various analyses and processing situations, the SFT-150 SFE is a full capability, research grade extractor. The SFT-150 is a versatile SFE, providing an excellent platform for process development. 

A new and important upgrade to the SFT-150 is the fully integrated waterless chilling technology to cool the CO₂ liquid prior to pumping  (patent pending). External cooling baths are no longer required.  Another system improvement is STF's newest, robust back pressure regulator for very precise CO₂ flow control.

The SFT-150 SFE’s modular design makes it easy and cost effective to alter the basic configuration, adapting it to meet new or evolving application needs. The SFT-150’s stainless steel vessel is capable of containing supercritical fluids at pressures up to 10,000 psi. The SFT-150 may be configured with hand-tight sample vessels ranging in capacity from 100 ml to 2 liters. Vessels are user interchangeable for maximum versatility. In addition, an optional co-solvent module can be added to the SFT-150.

The SFT-150 System pressurization is accomplished by an air regulator which controls the amount of air supplied to the pump, providing precise “dial in” pressure control. Through the application of heat directly to the pressure vessel and the use of an internal temperature sensor, the system’s PID temperature controller is able to provide precise temperature control while giving an accurate temperature readout.
