HOT Microfluidics is the leading provider of turnkey microfluidic solutions for enhanced recovery (IOR/EOR) and underground storage (hydrogen, carbon dioxide, natural gas) applications. The pioneering, fast and cost-effective ‘Rock-on-a-Chip’ approach provides unmatched process visualisation and optimisation, chemicals screening and yields an unrivalled understanding of fluid flow processes in porous systems.
We have invested in a fully equipped laboratory that puts us in a position to perform laboratory experiments using gases such as hydrogen, carbondioxide and hydrogen mixtures at reservoir conditions in compliance to highest HSE regulations.

Our laboratory equipment ranges from autoclaves to core-flooding rigs to microfluidics solutions.


We are a multidisciplinary team of:

  • Petroleum Engineers, Mechanical Engineers, Electrical Engineers, Software Engineers and Physicists


Whenever possible, we integrate Microfluidics Technologies into our Lab Services and Systems to:

  • Deliver experimental results up to 200 times faster
  • Significantly reduce cost
  • Significantly accelerate field project implementation
  • Significantly reduce required reservoir fluid volumes
  • Minimise laboratory and environmental footprints
  • Provide visual access to multi phase flow and interfaces
