The control of the freezing outcome and the characterization of its variability represents a major aspect of process design. For a system of pallet size, the effect of vial position within the batch needs to be studied in detail, since we observed differences in thermal evolution among core and side vials in both simulations and experiments (cf. Figures and). To achieve a system-scale understanding of the process, we report the temperature of all vials within vertical layers of the pallet at a few points in time in the form of heatmap snapshots.
