Efficient vitrification of mouse embryos using the Kitasato Vitrification System as a novel vitrification device

Table 1 The properties of the materials used for numerical simulations

Material	Density (kg/m³)	Heat capacity (J/kg•K)	Thermal conductivity (W/m•K)
Polyethyleneterephthalate film	1570	1260	0.31
Porous membrane^a	2170	1050	0.25
Vitrification solution^b	1255	1657	0.20
Thawing solution^b	1581	1255	0.28
Embryo^c	998	4182	0.60

^aPorous membrane is used as the vitrification solution absorber in the Kitasato Vitrification System
^bThe properties of the vitrification and thawing solution were referenced from a previous report by Tarakanov et al. [14]
^cThe properties of embryos matched those of water at 20 °C
