Abstract: Various implementations include a low temperature sample rod device for side entry electron microscopes. The device includes a conduction rod, a thermoelectric module, a coupler, and a thermal battery. The conduction rod has a first end configured to support a sample. The thermoelectric module has a first side thermally coupled to a second end of the conduction rod. The thermoelectric module is configured to transfer heat between the first side and a second side when supplied with electricity. The coupler has a first coupling surface thermally coupled to the second side of the thermoelectric module. The thermal battery has a battery coupling surface configured to be thermally coupled to a second coupling surface of the coupler. The thermal battery includes a material that can be melted from solid to liquid phase by heat transferred from the conduction rod, through the thermoelectric module, through the coupler, and into the thermal battery.
