A calorimeter assembly comprising Dewar flask means, a sealed vacuum container positioned in the bottom of the Dewar flask means and a sealed sample holding container positioned in the vacuum container provided with sump means and a gas removal tube connected to the sump means; the gas removal tube extending toward the top of the Dewar flask means and having a portion located outside of the vacuum container which portion includes spiral windings, and means for introducing fluids into the Dewar flask means and said sample container and means for regulating pressure in the Dewar flask means and for measuring gas flow from the sample container. The invention also includes the method of measuring heat loss by use of the calorimeter assembly set out in which the volume of gas emitted from the gas removal tube is compared with that volume of gas emitted for a known heat input.
