ExiGo Microfluidic Syringe Pump

ExiGo Pump series is a microfluidic syringe pump controlled by SmartFlo software that can be run from a PC. Connect up to four ExiGo pumps together with independent programming of each pump's flow profile.

  ExiGo Pump Instruction Manual 

Overview

ExiGo pump is a precision microfluidic syringe pump controlled by a PC via SmartFlo software. Comprising of a high-resolution stepper motor with patented pulse-damping and active feedback via optional flow sensor, it is suitable for microfluidic applications including, precise multichannel mixing, electrophysiology, single cell analysis, analytical biochemistry and RNA/DNA analysis. Key features of the ExiGo are:

• PULSE-FREE down to nL/min with flow sensor
• PROGRAMMABLE flow profiles with any combination of constant, ramp, sine and step
• EASY INTEGRATION with your own software, including LabVIEW, C++ and Python
• FAST SWITCHING: Response times as low as 50ms, significantly faster than standard syringe pumps
• FLOW RATES: 10nL/min - 13mL/min with an accuracy of ±0.5%
• STANDARD SYRINGES: 100µL - 5mL and automatic refill with ExiGo Manifold accessory
• CLOSED-LOOP FEEDBACK: Flow sensors provide active feedback and precise flow control
• MODULAR: up to 4 ExiGo pumps connected together with independent programming of each pump's flow profile.  Or you can mix-and-match with UniGo pressure pumps

An ExiGo Syringe Pump setup will look like this:

 

To select the ExiGo pump configuration you need use the selection chart below

1. Choose whether you want to control the ExiGo via a PC or for adding an additional ExiGo where you already have the software select additional model (SLA)
2. Select the optional flow sensor or use NS if you do not need one. The ExiGo flow sensor is plug-and-play and enables real time flow rate measurement. Once installed it will activate the PID control software options to improve the accuracy and dynamic response of the ExiGo pump.
3. Select if you want an option manifold for refilling the syringe or switching reservoirs. If not select NF to indicate no manifold is supplied with the setup. The ExiGo Manifold is a specialised microfluidic channel selector that allows the ExiGo pump to direct fluid to one of three microfluidic channels at at time. This can be used where you require
   • Automatic refilling of the syringe
   • Asynchronous injection of a reagent in multiple channels
   • Continuous perfusion over long periods of time
4. All systems come with a tubing kit and power cables
