The data set contains the information presented in Figure 6 of the paper, which shows the spin up and spin down times recored for saline solutions in the Eye-on-a-Chip device, for rotational velocities of 5 to 17 radians per second. Also shown in the figure are the viscous time scale and the Ekman timescale for the experimental conditions.

The experimental values were obtained by analysis of videos. The saline solutions contained small, almost-neutrally buoyant particles which allowed the local velocity to be determined. Examples of the videos are provided as Supplementary Information for the journal article.

The journal article will be published Open Access, and further information about data collection and data processing is given there.

The data are in a Microsoft Excel worksheet (.xlsx).
