Supercritical Fluid Technologies Inc. offers the SFT-150 Supercritical Fluid Extraction 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 includes a waterless chilling technology to cool the CO2 liquid prior to pumping, meaning that external cooling baths are not required. A back pressure regulator provides precise CO2 flow control.
The unit’s stainless steel vessel is capable of containing 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, and an optional co-solvent module can be added to the SFT-150. 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 temperature control while giving an accurate temperature readout.
