The SFT-Ultra High Pressure Digital Pump has been specifically designed for Analytical to high speed, high resolution Chromatography applications, in addition a constant pressure version has been developed to allow packing of particle in the 1 micron to 10 micron range. The analytical unit provides flow rates from 0.001 to 5.000 ml/min, with flow settings in 1 µl increments (18,000 psi.) The Packing pump has flow range settings from 0.001 to 12ml/min with flow controlled by the pressure setting. Pulse-free flow in the analytical pump is guaranteed by using advanced solvent recompression algorithms and automatic pressure compensation which provides unmatched performance for the most demanding applications.

The SFT-Ultra HP drive offers a linear cam and pressure compensation to provide accurate flow in the most demanding chromatography applications at normal HPLC pressures all the way to 18,000 psi.

The use of modern digital stepper motor technology and high performance mechanical design provide accurate flow rates and pressures over the entire performance range. In addition, all SFT pumps come with a 1-year warranty.

Standard controls include RS-232 serial communication port (for complete control and pump status monitoring) and Run/Stop inputs. Also standard are remote frequency & remote voltage controls and real-time pressure monitoring with user selected high and low pressure limits. The SFT-Ultra HP column packing pump comes with Quick set software for unmatched control of the packing process.

The SFT-Ultra HP Digital Pump is offered as a freestanding unit or in kit-form for OEM applications.
