Model Ultra CP Constant Pressure Pump, 0.01-12 ml/min. 18000psi

Model Ultra CP Constant Pressure Pump for Chromatography Column Packing

The Constant Pressure UHP Pump gives you the control to pack small particles, in the 1 micron to 10 micron range, with reduced shear and greater efficiency. The constant pressure pump allows constant packing pressures up to 5000 psi and 100 ml/min.

The use of a variable ramp speed setting allows the user to choose the best flow profile for a given packing. The Model CP reduces turbulence and shear during the packing process, leading to more uniform bed structures and less fines generation than traditional methods of packing using high-pressure pneumatic amplifier pumps. The packing pressure can be monitored during the process to verify performance.

The pump has RS232 or simple keypad control and a digital stepper drive for precise flows and pressures. A column packing system is also available for use with the model CP.
