Improved Supercritical Fluid Extractor

Supercritical Fluid Technologies (USA) have introduced a new bench top supercritical fluid extractor (SFE), the model SFT-110XW. This latest addition to the SFE product line builds upon the predecessors, the SFT-100 and SFT-100XW. The completely redesigned restrictor valve with integrated micrometer allows for precise flow control, which is essential for demanding applications. A completely removable oven lid and large side panel allow the user easy access to the high pressure vessel(s). An indicator light on the SFT-10 pump module alerts the user to proper operation of the Peltier pre-cooler, ensuring CO2 is maintained in the liquid state. A robust outlet from the restrictor ensures that users will not accidently damage the outlet tube when inserting it into the collection container. Extraction vessels up to 500 ml, single or dual configurations, afford maximum versatility.

Supercritical fluid extraction has become a popular alternative to traditional extraction methods that use organic solvents. Fast, efficient extraction of a variety of materials may be achieved using supercritical carbon dioxide. The SFT-110XW SFE is well suited for both research and process development applications. Precise control of temperature, pressure, and flow rate is essential for successful, reproducible extractions. The use of dual sapphire syringe pump technology, integrated pre-heaters, and precise flow control provides the precision required to achieve these goals. Process parameters developed in the laboratory are the key to the successful scale-up to pilot or production scale equipment.
