CP Class

The  high  performance  CP  Class  consists of  dual-headed,  positive displacement  piston  pumps  with  constant  pressure  control,  covering  a  wide  range  of  fows,  with  pressures  up  to  25,000  psi.    Standard  fuid  path materials  are  Stainless  Steel  and  optional  Titanium.    Other  available  features include  jacketed  heads  for  temperature  controlled  processes.

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 fow 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 fow rate limit.

The CP Class is available as standalone units, and also with the 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 and

Micro USB 2.0 ports. With 5 mL/min, 12 mL/min, 24 mL/min, 100 mL/min, and 300 mL/min versions, the CP Class will meet most LC Column packing and process needs.
