Overview

Many micro and nano-fluidic applications require smooth, non-pulsatile and stable flow inside microfluidic biochips. This cannot be achieved by many standard syringe pumps due to the design which includes a stepper motor whereby a step (or micro-step) delivers a defined volume dependent on the syringe size connected. Cellix's novel patented ExiGo microfluidic pump can deliver precise non-pulsatile (pulse-free) flow rates in the nano to microfluidic range, even while using a standard 5mL plastic syringe. Where standard syringe pump providers claim they can deliver such flow rates; it is often only when coupled with a syringe in the microlitre range thereby limiting the experiment for the user.

The ExiGo syringe pump is a top-level fluidic precision pump available to the market and stands out for portability (reduced volume and weight), ease and intuitive use (controlled via Wi-Fi using an iPad mini), quick setup, independent control of up to 4 outlets and accuracy at very low flow rates. The ExiGo offers additional control options giving the user the ability to completely customize the perfusion profile choosing among several functions such as step, ramp, linear or sinusoidal. The ExiGo pump also has a feedback controlled option when connected to the ExiGo sensor for an enhanced control of the perfusion with flow rate real-time monitoring.
