Hi,

Here we have an excellent condition SFT-120XW that came from Full Cycle Bioplastics. It is complete with Nex10 pump, metering doping pump, CO2 tank, regulator, a 100ml and a 1000ml reactor, both with heaters, thermocouples, and installation kits. The XW can take from 5ml to 1000ml vessels and can expanded to 2 or 4 vessels operating simultaneously in series or parallel.

This unit is ideal for analytical, R&D and/or small scale production of supercritical CO2 extracted fluids.

We will set-up and rent for a days of extraction for $1000.

Please visit Supercritical Fluid Technologies website for more information.

There are also many videos on you tube available by searching SFT-120.

The SFT-120XW Supercritical Fluid Extractor (SFE) is an entry level system which possesses many features typically found in more costly Supercritical Fluid Extraction equipment. It may be used for a variety of applications from routine analytical work to basic process development.

The SFT-120XW was developed for people who want to investigate the feasibility of applying supercritical fluid extraction techniques to a wide variety of analytical and processing problems. In addition to its numerous industrial uses, the SFT-120XW 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-120XW accommodates 5 ml to 1000 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-120XW well suited to both analytical scale Supercritical Fluid Extraction applications and basic process development work. With a 500 or 1000 ml vessel, the SFT-120XW 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-120XW’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-120XW 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.

Manually operated valves ensure long term, maintenance free operation. An integrated program logic controller monitors and adjusts fluid pressure inside the extraction vessel to achieve and maintain a desired set point. A PID temperature controller monitors and maintains the precise fluid temperature inside the high pressure vessel.

A robust, variable restrictor valve (back pressure regulator) provides precise control over flow rates, which is essential in obtaining highly reproducible results from run to run. Flow rates can range from 0.01 to 50.00 ml/min of liquid CO₂ under typical operating conditions. While carbon dioxide is the most commonly used solvent, the SFT-120XW, with some modification, allows the user flexibility to work with a variety of supercritical fluids.

Extract collection options include: solid phase extraction (SPE) cartridges, fractional cyclone separators, and EPA sample vials. An optional co-solvent addition module is available for the SFT-120XW.
