Fig. 4.

Shake speed and orbital size versus pellet size. Differences between baffles, coils, common flasks, shake speeds and flask volume. Based on these data we see no differences between coils and baffles (a) or between different inoculation volumes (d). However clear differences in pellet size were observed between unbaffled and baffled flasks (b) and when the orbital shaking speed was adjusted (c). Plotted are the average diameter versus the polar circularity; circles represent the 95% confidence intervals
