Supercritical Fluid Technologies, Inc. has introduced the completely self-contained SFT-10 Liquid Carbon Dioxide Pump, boasting advanced Peltier (thermoelectric) technology that makes it possible to achieve high pressure without the need for an external cooling bath.

The SFT-10 pump can deliver carbon dioxide at pressures up to 10,000 psi (69 MPa) at flow rates from 0.01 to 24.0 ml/min. These characteristics make the SFT-10 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 SFT-10 utilizes reliable, dual sapphire syringe pump technology to achieve high pressures rapidly, while the Peltier chiller has superior cooling capability. It 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.

The SFT-10 may be acquired as a stand-alone CO2 pump or used as part of Supercritical Fluid Technologies’ SFT-110 / SFT-110XW Supercritical Fluid Extractors.
