• CO₂ bubble chain
• Air bubble chain
• Liquid velocity with air bubble chain
• Concentration measurements with air bubble chain

In these experiments air bubbles were generated at 2 and 4 l/h gas flow rates.

For these experiments, a mixture of de-ionized water, resazurin, glucose and sodium hydroxide was used as liquid phase.

These experiments were carried out in the following mixture:
