Fusion 4000-X Dual Independent Channels Syringe Pump

Fusion 4000X
Syringe Pump


The Fusion 4000X is a motorized, multi-channel syringe infusion pump. It features a dual-independent channel infuse and withdraw syringe pump. It is built with 2 separate pump drives capable of independent pulseless, reproducible rates, and movement. Programmable multi-step and cycle mode that allows users to input complex flow profiles or perform flow cycling from a computer Labview or the pump itself. This motorized multi-channel syringe infusion pump system also can be expanded with a 2-syringe push and pull rack attachment to increase the total syringe capacity to four.
Designed for a wide range of biopharmaceutical research like lipid nanoparticles, microfluidic mixing, and lab-on-chip flow control in drug formulation applications; with an all-glass touch screen and precision machined metal design, the Fusion 4000-X dual-channel syringe pump is easy to clean, for lab and GMP environments.

Frequently Asked Questions

Can the 2 syringe channels work independently?

Yes, the 2 syringe channels can operate independently. You have the option to start 1 channel individually or initiate both simultaneously. Additionally, the syringe pump can function in cycle mode, wherein the two channels alternate the flow in a push-pull fashion. This involves one channel infusing forward while the other withdraws backward.

What is the min and max syringe size?

0.5µL(min) to 60mL(max)

What syringes are compatible?

Any syringe that will fit under the syringe clamp can be used with the system regardless of material or construction. Plastic, glass, and stainless steel syringes are all viable options. See also Syringe Type Chart.

What are the min and max syringe flow rates?
  • 0.0001 µL/min (with 0.5µL syringe)
  • 85 mL/min (with 60mL syringe)
What type of PC control connections are available?

USB, RS232 and TTL Ports – The system communicates to PC’s via ASCII text commands. For help programming the system please see the Chemyx programming SDK link.

What computer control SDK packages are available?
Which type of multi-syringe racks are available?

This clamp fits on 1 channel of the system while the other channel can retain the default clamp.

What is the warranty?

A 2-Year Warranty* comes standard with all Chemyx programmable syringe pumps.

Dual Independent Pump Channels

The Fusion 4000-X multi-channel 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 multi-channel 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.

Fusion 4000 Syringe Pump
Complex Flow Controls

The Fusion 4000-X multi-channel 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 multi-syringe pump 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 multi-channel syringe pumps are precision machined with metal components for a level of accuracy needed for micro flow 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 limited* warranty

Programming Fusion 4000 Syringe Pump
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, RS485, TTL
  • LabVIEW and MATLAB drivers available

How Do Chemyx Syringe Pumps Work?

A syringe pump is a small, positive-displacement pump used to gradually transfer precise volumes of fluid. Chemyx Fusion Series syringe pumps are all driven via a stepper motor. A lead screw, threaded through a pusher block, precisely turns the pump’s stepper motor. This causes the pusher block to move. The fluid ejects at an accurate […]

Common Reasons For Syringe Leakage

The components of even the most durable syringe will eventually fail. The most common symptom of failure may be leakage of your solvent from the syringe. The following are some common reasons for syringe leakage, as well as our recommended solutions. 1. Tip Connection The most common symptom of failure may be leakage of your solvent from the syringe. If your syringe […]

What To Do If Your Chemyx Syringe Pump Stalls?

If you are starting to experience stalling issues with your Chemyx syringe pump system, there are a few questions to determine the root cause and get your motorized syringe pump working again. Does the pump stall without any syringes? If not, then the stall may have been caused by too much back pressure. Try using a smaller syringe and/or setting […]
