    Flow adjustment in 0.01 ml increments, from 0.01 to 10.00 

ml/min with a precision of 0.2% RSD (10mL/min heads) 

•

  Microprocessor advanced control 

•

  Digital stepper motor design to prevent flow rate drift 

over time and temperature 

•

  Back panel RS232 serial communications port for 

complete control and status monitoring 

•  Remote analog inputs (e.g. voltage) to control flow rate  

Pump heads, check valve bodies, and tubing are made out Stainless 
Steel or PEEK™.  Other materials are synthetic ruby and sapphire 
(check valve internals and piston). 

 
Self-flushing pump heads provide continuous washing of the piston 
surface without the inconvenience of a manual flush or gravity feed 
arrangement. The self-flushing pump head uses a diaphragm and  
secondary set of check valves to create a continuous and positive flow 
in the area behind the high pressure pump seal.  The flushing solution 
washes away any buffer salts that have precipitated onto the piston.    
If not removed, these precipitates can abrade the high pressure seal 
and cause premature seal failure, leakage, and can possibly damage the 
pump.
