A compact low cost cooling stage for lab based x-ray micro-CT setups

A temperature controlled sample stage, which can both heat up, and cool down a sample while it is subjected to a μCT scan has been developed. The stage was designed to reach temperatures up to 50°C and down to −20°C and has been used in several applications with a varying degree of dynamism, going from immobilizing samples by freezing them to studying fully dynamically evolving temperature dependent processes.
