Figure 1: Examples of differential scanning calorimetric thermograms during the warming process of water-Ficoll 70-DMSO model solutions with different weight ratios of Ficoll 70 and DMSO and the same total solute ratio as 50% (w/w).

The characteristic temperature transitions of these model solutions are marked: vitrification temperature (Tg), devitrification temperature (Td) and melting point (Tm). A scale bar (10 mW) is provided to evaluate the magnitude of heat flow during each phase transition stage.
