- Dual Serial Pistons - provide low pulsation and greater seal life.
- Low Volume Piston Displacement - 10 µL per plunger stroke, gives a noise profile matched to electrochemical detector noise filtration.
- Flow Rate Range of 0.001 - 9.999 mL/minute - usable for microbore and analytical separations.
- Automatic Seal Wash - prolongs piston seal life for greater reliability.
- Enhancement Package - for reduced noise with electrochemical detection.
- Electronic Diagnostics - for easier maintenance.
- Improved Fluidics - made more reliable and easier to service
- High Gradient Accuracy and Precision - for greater reproducibility
