N.59 – Hole impact distribution

TRIO

Even distribution of air flow on the agar of Petri dish

The purpose of the test was to verify the regular distribution of the air flow on the surface of agar of a 90 mm Petri dish. The evaluation is performed counting the number of the impact holes produced on the gar surface, after aspiration.
