An attempt was made to discriminate between two hypotheses (standing wave, bubble recycling) of the mechanism of ultrasonically induced cell lysis in a rotating tube. A tube containing an aqueous suspension of P‐388 cells was moved back and forth (+/‐ 3 or +/‐ 7 mm) during insonation (1 MHz, 5 W/cm2, continuous wave, 5 min). Cell lysis (approximately 20%) occurred. As a positive control, some tubes were also partially or completely rotated during insonation; considerable cell lysis (approximately 60%) occurred. The results are interpreted to suggest that both hypotheses are simultaneously useful in explaining the observed effect of cell lysis in a rotating tube.
