Cellix's ExiGo Microfluidic syringe pump vs. conventional syringe pumps

What is the ExiGo pump?

The ExiGo pump is a microfluidic pump that can push the sample fluid in a syringe through tubing, and into a microfluidic chip, or pull fluid from the microfluidic chip into the syringe. Cellix's SmartFlo software control includes easy programmable features for to your experimental needs, whether you need a steady flow or a custom flow.


How does the ExiGo pump work?

With a syringe inserted, the 5-phase stepper motor rotates the screw, moving the pusher block against the syringe plunger. Changing the rotation allows you to change the direction of flow, in or out of the syringe.

  1. When the Stepper Motor turns, it causes the Lead Screw to turn

  2. When the Lead Screw turns, it moves the Pusher Block against the Syringe Plunger

  3. For dispensing (or pushing), the Pusher Block moves to the right, pushing fluid out of the Syringe and into the Microfluidic Chip

  4. For aspirating (or pulling), the Pusher Block moves to the left, withdrawing fluid into the Syringe and out of the Microfluidic Chip

What makes the Cellix ExiGo pump special?

While other pumps use unreliable 2-phase stepper motors, the ExiGo pump uses a state of the art 5-phase stepper motor. The 5-phase stepper motor has a smoother motor with a much greater number of step increments per revolution, giving a noticeably smoother operation, with low noise and low vibration. This is ideal for labs that need greater accuracy, precision, and reliability.

It doesn’t just stop at the motor, the ExiGo pump works across devices for ease-of-use, and is programmable to give you full control over fluid flow. Not only that, the ExiGo pump is modular and supports up to 4 concurrent pumps with individualised programming.

Some key features of the ExiGo pump include :

  • Fast Switching : Not all syringe pumps are slow! Response time as low as 50ms
