  • Method for freezing-point determination
    Patent number: 4657409
    Abstract: A method for measuring the freezing point of a liquid utilizing non-adiabatic thermodynamics for the chilling chamber. The temperature of the chilling chamber in which the measurement is made is actively altered to reduce net heat flow from the sample portion of the liquid being measured at least during nucleation of the sample portion. By actively altering the chilling-chamber temperature, the thermodynamics of the sample itself more nearly approach a true adiabatic condition during nucleation. Preferably, the freezing-point measurement is made in the sample-handling or pick-up device itself.
