Small Production Supercritical Systems

2-TECH-L/S

Multipurpose, Expandable SFE Pilot System

The 2-TECH-L/S is a multipurpose, movable pilot plant/small production system. The system has been ingeniously designed to process both solid/semi-solid samples and liquid samples. Solids are extracted in batch by a 5 liter (or 2 liter) extractor vessel and cyclone separator. Liquids are extracted through a counter-current column where supercritical CO₂ flows counter-current to the flow of a liquid containing the compound of interest. Through a crossover network, extract from the solids extractor vessel can also be sent to the counter-current column.

Although most supercritical fluid extractions are accomplished using carbon dioxide, other gases can also be used. The 2-TECH-L/S system supports the supercritical fluid extraction by other gases as long as facilities modifications are made.

Accessories for the 2-TECH-L/S

Spe-ed Max Modifier Pumps
Polar modifiers, such as methanol or ethanol, can be added to the non-polar supercritical CO₂ to improve the recoveries of some polar analytes. The Spe-ed Max pumps accurately meter solvents into the SCF stream.

Spe-edRCB
The Spe-ed RCB is a specially designed recirculating cooling bath that chills the CO₂ to liquidity. This makes for efficient use of CO₂ with all Applied Separations SFE systems.
