Sparger gas delivery

The physical interface — typically a porous or perforated diffuser — through which blended gas enters a bioreactor's culture broth as bubbles, affecting mass-transfer efficiency and shear stress on cells.

Where it's used

Bioreactor gas-mixing systems
Mass flow controllers and gassing installations that blend oxygen, carbon dioxide, nitrogen and air to precise setpoints and deliver them through a bioreactor's sparger — the subsystem that stabilizes dissolved oxygen and pH and is directly implicated in batch-to-batch yield variability when gas control drifts.
