Description
Summary:There is growing interest in using isochoric freezing and isochoric supercooling for the preservation of biological matter at subfreezing temperatures. Custodiol® is a commonly used intracellular composition type, subnormothermic preservation solution. It is anticipated that Custodiol® will also be used for isochoric freezing and isochoric supercooling preservation of biological matter. The thermodynamic properties of Custodiol® at subfreezing temperatures as well as the metastable behavior of the solution at subfreezing temperatures were not studied in the past. This study was designed to generate the thermodynamic data needed for the use of Custodiol® for the preservation of biological matter in isochoric systems at subfreezing temperatures. The experiments were performed in a specially designed isochoric chamber that can measure simultaneously the temperature and pressure in the isochoric chamber, and thereby correlate pressure and temperature at thermodynamic equilibrium in isochoric systems as well as the nucleation temperature in isochoric supercooling. The primary focus of this study is on determining the temperature at which nucleation is initiated and to identify the temperature threshold for nucleation due to its specific relevance to various applications in medicine.
