EC-Compatible Isocratic Micro-Displacement Pump

Optimized for HPLC electrochemical detection with the Coulochem III detector. The ISO-3100BM pump offers pulse-free solvent delivery – even at micro-flow-rate ranges below 50 μl/min – and offers the following features and benefits:

Dual parallel plungers – provide low pulsation and greater seal life
Micro-volume plunger displacement – 25 µL per plunger stroke, improves limits of electrochemical detection
Flow rate range of 0.001 - 2.5 mL/minute – can be used in analytical, microbore, and LC-MS separations
Automatic seal wash – prolongs plunger seal life for greater reliability
Enhancement package – for reduced noise and lower limits of detection with all HPLC detectors
Electronic diagnostics – for easier maintenance
Improved fluidics – more reliable and easier to maintain
High accuracy and precision – for greater reproducibility
