Patent ID: 7802916

Claim:
A differential scanning calorimeter comprising: a heating furnace of an approximately H-shaped cross section having an approximately drum-shaped wall part to cover the surroundings and an approximately plate-shaped heat inflow part to be formed at the inner circumference of the wall part, wherein the heating furnace is disposed with a center axis approximately vertical; a heater disposed at the outer circumference of the wall part and to heat the heating furnace; an approximately bar-shaped heat-resistance member that is vertically arranged along the center axis of the heating furnace, that protrudes by an approximately equal length from both sides of the heat inflow part, that is secured at the heat inflow part, and that is made of a material with heat conductivity lower than that of the material of the heating furnace; a sample container disposed at one end of the heat-resistance member so as to contain a measured sample; a reference container disposed at an opposite end of the heat-resistance member; and a differential heat flow detector detecting a difference between the temperature of the sample container and the temperature of the reference container as a measured value.
