1. A method of dispensing liquefied gas solution comprised of a liquefied gas solvent having a vapor pressure above 100 kPa at a temperature of 293.15 K, from a liquefied gas solution container to a secondary container through a first valve, an intermediate container, and a second valve, wherein liquefied gas solution container comprises a temperature sensor to detect the temperature of the liquefied gas solution container, the method comprising:
a. opening the first valve to allow liquefied gas solution to flow from the liquefied gas solution container into the intermediate container;
b. filling the intermediate container completely;
c. during steps (a) and (b), maintaining the liquefied gas solution container and the intermediate container at an equal temperature;
d. closing the first valve;
e. opening the second valve to allow liquefied gas solution to flow from the intermediate container into the secondary container;
f. taking readings from the temperature sensor; and
g. based on the temperature readings, heating the intermediate container to maintain the temperature of the liquefied gas solution container at a predetermined temperature or within a predetermined temperature range;
wherein the predetermined temperature or temperature range in step (g) is selected to create a temperature differential between the intermediate container and the secondary container, thereby transferring the liquefied gas solution from the intermediate container into the secondary container.
