Accudyne Systems, Inc. is the engineering, design and production partner for Supercritical Fluid Technologies, Inc. SFT is an innovative laboratory equipment company that offers a full line of Supercritical CO2 extraction and reaction equipment.

Whether it's repetitive laboratory exractions or process development and optimization, the SFT-150 provides an excellent introduction to the power and versatility of SFE/SFR technology. Offering the flexibility and safety features often found only in higher priced extraction systems, the unit aids in investigating the feasibility of applying supercritical fluid techniques to various analyses and processing situations without incurring the larger capital investment required for more automated and integrated systems. The SFT-150 comes standard with a 100 ml hand-tight sample vessel and is unique in its ability to accommodate pressure vessels up to 4 liters in capacity. A larger processing vessel enables the user to extract very low levels of key components from materials or process larger amounts of bulk material than would be possible with conventional, analytical scale SF equipment.

The SFT-250 SFE/SFR Processing System was engineered to meet the day-to-day rigors of the research laboratory and may be used for small-scale pilot processing. This unit is simple to operate, easy to modify for evolving application needs, and features many of the performance characteristics of our fully automated SFT-1000. Accommodating pressure vessels of up to 4 liters in size enables the user to extract very low levels of key components from materials or process larger amounts of bulk material than would be possible with conventional, analytical scale SF equipment. Additionally, the SFT-250 may be configured with multiple vessels that may be operated simultaneously, either in series or in parallel. Vessels are easily interchangeable by the user.

At the top of SFT's product line, the SFT-1000 offers more flexibility and automation features than any other supercritical fluid extraction/reaction instrument available today. A built-in PLC (Programmable Logic Controller) controls co-solvent addition, pumping rates, pressures, temperature zones, mixing, valve actuation, and safety interlocks. It is capable of storing up to 20 user -defined method programs and allows method modification while the system is running. A bi-directional RS232C interface permits data and methods to be transferred to and from an external computer. The SFT-1000 can accommodate pressure vessels of up to 4 liters in the bench scale version and up to 5 gallons in the rack-mounted configuration. The SFT-1000 may be configured with multiple vessels capable of simultaneous operation either in series or in parallel. Vessels are easily interchangeable by the user. The extract collection assembly, which may be a solid phase extraction (SPE) cartridge, a solvent filled vessel, or a fractional cyclonic separator, is mounted outside the main cabinet or rack providing ready access for the user and simplifying the interface to other instrumentation such as an HPLC or mass spectrometer.

Safety is a primary concern of all units. Interlocks provide safety precautions, preventing over temperature or over pressure conditions. As an additional safety precaution, rupture disc assemblies provide mechanical protection against accidental over pressurization of the system. Conveniently located panels allow easy access to the pressure vessel, valves, fittings, and electronics. Valves operated manually or by air provide long term, maintenance free performance.
