We use the data from run 4 (duration of about 40 h at -40°C), to estimate T sp = -15°C. Eqn. 21 then predicts a five-fold increase in process duration when increasing the storage temperature to -20°C, in agreement with the experimentally observed trend (duration of about 200 h at -20°C). It also correctly predicts incomplete freezing for run 3 at -25°C. We thus confirm that the simplified model may be a useful practical tool to predict the effect of both storage temperature and nucleation kinetics on process duration.
