Differential thermal analysis studies have resulted in quantitative evaluation of the transformation kinetics of unstable glassy phases formed during cooling of solutions from equivalent isoplethal sections. These ternary systems are of particular importance in the field of cryobiology, where knowledge of glassy phase may be especially crucial for long-term storage of biological materials at cryogenic temperatures. Activation energies for devitrification of glasses in both systems have been determined. The glasses were found to have approximately equal long-term stabilities. The DMSO-containing glasses appear to be more complex than glycerol-containing glasses.
