Pump Achieves High Pressure Rapidly
ith advanced Peltier (thermoelectric) technology, the SFT-10 Liquid Carbon Dioxide Pump reportedly makes it possible to achieve high pressure without the need for an external cooling bath. The pump can pressurize carbon dioxide up to 10,000 psi (69 MPa) at flow rates from 0.01 to 24.0 ml/min. It is intended for use in supercritical fluid extraction and a variety of other high pressure applications. The dual sapphire syringe pump technology helps achieve high pressures rapidly. The Peltier chiller maintains the temperature at the pump heads low enough to ensure the carbon dioxide remains liquid.
