Model CP24 Constant Pressure Pump, 0.01-24 ml/min. 10000 psi

Model CP24 Constant Pressure Pump for Chromatography Column Packing

The Model CP24 is a high pressure dual piston pump utilizing a constant pressure mode of operation to efficiently pack small diameter packing materials and smaller diameter columns. The constant pressure pump allows constant packing pressures up to 10,000 psi and 12 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.
