We present in this talk recent ultralow temperature experiments performed on superfluid 3He, the instruments we use to cool this system to temperatures as low as 100 microkelvins, the limitations encountered in a ground laboratory, and the benefits expected from the operation of our ultralow temperature instrument in the Canfranc underground laboratory. Superfluid 3He is considered to be the most sophisticated condensed matter system well understood by physicists. Its theoretical description involves orbital, symmetry, and gauge broken symmetries. It has therefore a tremendous potential for guiding our intuition in complex problems, like the dynamics of second order phase transitions, topological defects creation, high Tc superconductivity and heavy fermions, among others.
