The CP Class pumps are widely used for LC Column packing, as well as many process applications. The constant-pressure feedback loop automatically adjusts solvent flow to maintain constant system pressure and allows the user to select a wide range of process parameters, including desired pressure set point, ramp rate, and upper flow rate limit.

The CP Class is available as standalone ​units, and also with the SSI Column Packing System (called Pack-in-a-Box). Features include an integrated Prime-Purge Valve, interactive keypad control, advanced pressure control algorithms, and complete PC control and status ​through RS-232, Ethernet, and Micro USB 2.0 ports. With 5 mL/min, 24 mL/min, and 100 mL/min​ versions, the CP Class will meet most LC Column packing and process needs.​​
