Storage tank where (surplus, or leftover) frozen embryos from IVF are stored
Not very sexy, but it works

After the embryos are frozen in the controlled-rate
freezer in special straws, they are immersed
and stored in liquid nitrogen in this tank.
Liquid nitrogen is -196ºC (or -320ºF). That's cold...
When the couple is ready to use their frozen embryos we thaw them and put them back in her uterus.
