Ultra-High Pressure (UHP) Legacy HPLC Pump

Accurate Flow Rates for Pressures up to 18,000 psi

The Ultra High Pressure Digital Pump has been specifically designed for Analytical to high speed, high resolution ​Chromatography applications.

The UHP Pump provides flow rates from 0.001 to 5 mL/min, with flow settings in 1 μL increments. Pulse-free flow in the UHP Pump is guaranteed by using advanced solvent recompression algorithms and automatic pressure compensation which provides unmatched performance for the most demanding applications. The Ultra HP Digital Pump is offered as a freestanding unit or in kit form for OEM applications.

Ultra-High Pressure Legacy HPLC Pump

Easy Control

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 Ultra HP column packing pump comes with Quick set software for unmatched control of the packing process.

Accuracy Over the Entire Pressure Range

The 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. ​
