Entry Level SFE for Universities and Industry

The SFT-110 XW Supercritical Fluid Extractor (SFE) is an entry level system which possesses many features typically found in more costly SFE equipment. It may be used for a variety of applications from routine analytical work to basic process development.

The SFT-110 XW was developed for people who want to investigate the feasibility of applying supercritical fluid techniques to a wide variety of analytical and processing problems. In addition to its numerous industrial uses, the SFT-110 XW is well suited to the needs of colleges and universities. It is so affordable that it may be incorporated into teaching laboratories. At the same time, it is capable enough to be used for serious research.

The SFT-110 XW accommodates 5 ml to 500 ml extraction vessels. It may be operated at pressures up to 10,000 psi (68.9 MPa) and at temperatures ranging from ambient to 200°C. The wide range of vessel volumes available makes the SFT-110 XW well suited to both analytical scale SFE applications and basic process development work. With a 500 ml vessel, the SFT-110 XW can extract very low levels of key components from materials and process larger amounts of bulk material than would be possible with smaller, analytical scale SFE equipment. Inside the SFT-110 XW’s oven, a preheater ensures that the temperature of the fluid reaching the extractions vessel is controlled precisely. This is essential to obtaining accurate, repeatable results.

The SFT-110 XW incorporates a high performance, dual piston pump which produces the high pressures required for supercritical fluid work. The system has built-in safety precautions to prevent accidental over-temperature or overpressure conditions. As an additional safety backup, a rupture disc assembly provides mechanical protection against accidental over pressurization of the system.
