Supercritical Fluid Digital Pumping System

The APP Supercritical Fluid Digital Pumping System (SFDPS) provides accurate pressure generation and control up to 3000 PSI (pneumatic system). The SFDPS is an open system that allows a liquid, typically liquid CO2, to pass through a sample at a user-defined pressure, thereby extracting a desired component. The sample is held in a chamber connected to the SFDPS. We can custom design and provide this chamber to form the complete Supercritical Fluid Extraction System. Alternatively, the chamber can be obtained elsewhere and fitted to the SFDPS.
