A device for unsealing a sample pan for a thermal analysis instrument includes a sample pan holder, an actuator element and a punch element. The sample pan holder is configured to secure the sample pan in a fixed position with respect to the sample pan holder. The actuator element is secured to the sample pan holder and is formed of a thermally sensitive material that changes the shape of the actuator element in response to a change in an external temperature to a transition temperature. The punch element is attached to the actuator element and is positioned with respect to the sample pan such that the change in the shape of the actuator element in response to the change in the external temperature moves the punch element to puncture the sealing element to thereby expose the internal volume of the sample pan to an external environment.
