High pressure syringe pump

This high-pressure equipment is integrated into a fluidic system for the study of physico-chemical conditions that may have played a role in the emergence of life on Earth, simulating pressure and temperature conditions akin to deep-sea hydrothermal sources.

The pumps are coupled with microfluidic devices developed at ICMCB. The goal is to precisely control the continuous flow of fluids over a range from very low rates to feed the microfluidic device (~0.1 µL/min) to higher rates (~50 mL/min), aiming to represent the pressure conditions of the studied environments.

The ultimate objective is to achieve a laboratory setup (pumps + mini-reactor + characterization) that faithfully represents natural processes.

Technical Specifications of the Syringe Pump

The syringe pump can be used in a vertical or horizontal position depending on the integrated process. It enables the injection of a fluid at a constant and precisely stable flow rate, consisting of two main elements:

• Motorized syringe pump
  Interchangeable syringe (10 mL – 25 mL)
• The syringe can be replaced with another of a different volume.
