• High precision

4
Easy Maintenance

• Modular design
• Simple seal changes
• Self flush is standard
• Pumps are on pull out drawers
• Each pump is independently serviceable

5
Fluid Path Fully Accessible

• Easy Set up
• Connect inlet lines
• Connect line to Injector
• Prime pump
• 200ml Delay
• Ez Prime in head PPV

6
Simple Front Panel Control

• Can select and set
• Flow
• Max pressure limit
• Low pressure limit
• Allows monitoring
• Pressure
• Flow
• Start or stop the pump

7
EZ Prime

• Allows each head to be primed independently
• Can prime head while other pump is running

8
High Performance

• Dead volume is minimized
• 0.001ml/min flow resolution
• Out gassing effects minimized since mixing is on
  high pressure side of pump
• Precise digital control of each solvents flow
• Use data system interface for control or keypad
  controller
