System Features

Dual Independent Pump Channels

The Fusion 4000 syringe pump comes with a dual drive system to allowing two independent pumping channels to be controlled for simultaneous infusion and withdrawal at same/different flows. This allows both syringes to operate in a variety of different ways to accommodate a wide range of applications.

The Fusion syringe pumps infuse and withdraw solutions at extremely high precision, and has reproducible flow rates via a state of the art microstepper motor. Easily and effortlessly deliver a wide range of flow rates in precise amounts for a multitude of applications like microfluidics, injections into a reactor, mass-spec calibration, and neuro-drug delivery to animals.

Complex Flow Controls

The Fusion 4000 syringe pump allows both channels to be controlled independently.  This allows the system to dose variable size syringes at different rates, for example, a saline & drug combination infusion or a catalyst & co-catalyst reagent addition into a reactor.  Additionally, the Fusion 4000 also comes with continuous cycle mode (push-pull functionality) that will oscillate the syringe the 2 pump channels to provide non-stop flow.

Resistant Glass Machined Components Built to Last

Chemyx pumps are precision machined with metal components for a level of accuracy needed for microflow applications and for both chemical resistance and mechanical wear. Chemyx high precision pumps last for years with an equipment value that is hard to match.


  • Machined metal design
  • Chemical resistant polypropylene coated screen
  • 2-year warranty
Programmable & Intuitive

Intuitive, user-friendly software lets users program and customize flow profiles and offers a robust database of brand-name syringes. Remote computer control capabilities are available through USB, TTL, and RS232 communication connections.


  • Programmable variable rate profiles via keypad
  • Computer control via USB, RS232, TTL
