We report the results of the first systematic study of the phase separation from supersaturated 3-4He liquid mixtures of dilute phase in the temperature range from 130 mK down to 400 μK. We find that the degree of critical supersaturation becomes almost temperature independent below about 10 mK while it increases with temperature above about 10 mK.
