The completely self-contained SFT-10 Liquid Carbon Dioxide Pump features advanced Peltier (thermoelectric) technology that makes it possible to achieve high pressure without the need for an external cooling bath. The unit can pressurize carbon dioxide up to 10,000 psi (69 MPa) at flow rates from 0.01 to 24.0 ml/min. These characteristics make the product an ideal pump for use in supercritical fluid extraction and a variety of other high pressure applications, including supercritical fluid reaction chemistry and chromatography. The product utilizes reliable, dual sapphire syringe pump technology to achieve high pressures rapidly. The Peltier chiller has superior cooling capability and maintains the temperature at the pump heads low enough to ensure the carbon dioxide remains liquid. The standard operating mode is "constant pressure" where the pump will maintain a pressure set point. An optional constant flow mode, from 0.01 to 24.0 ml/min., is available.
