Gas Dispersion Tube
Gas Bubbler with a Sintered Porous Glass Frit
Maintain reproducible reaction conditions, or remove dissolved oxygen before sensitive experiments
Specifications | Gallery | Pricing | Related Products | Technical Support
A gas dispersion tube or a bubbler is a slender tube fitted with a sintered glass frit at the tip, used to introduce and disperse gas into the electrolyte as a fine stream of bubbles. The frit breaks the gas flow into small, evenly distributed bubbles, maximising gas-liquid contact area and improving mass transport to and from the electrolyte. Available in two lengths, 45 mm and 60 mm, to accommodate different cell depths and electrode configurations compatible with Ossila Electrochemical Cells and similar products.
The dispersion tube supports three distinct functions, depending on the experiment:
- Purging: Remove dissolved gases (typically oxygen) from the electrolyte before an experiment begins, using an inert gas such as N₂ or Ar. This is standard practice before HER and OER studies, where dissolved O2 can interfere with electrode kinetics or introduce background reduction currents.
- Saturation: Pre-equilibrate the electrolyte with a specific reactant gas so its dissolved concentration reaches a known, stable value before measurement begins. This is essential for CO2RR, where the electrolyte must be CO2-saturated, and NRR, where N2 saturation defines the available nitrogen feedstock. Similarly for ORR, where the electrolyte must be O2-saturated.
- Sparging: A continuous gas flow is maintained throughout the experiment, replenishing gas consumed at the electrode surface and holding a steady dissolved gas concentration during extended CO2RR, ORR, or NRR testing.
