The Caron 7900 series Freeze Thaw Chamber is an insulated chamber that allows us to conduct controlled climate experiments to examine how materials behave under different conditions. This chamber can be used to simulate stressing conditions such as freeze-thaw cycles or humidity fluctuations. The Freeze Thaw Chamber is completely programmable, and can be set to follow an ASTM standard, or to simulate the climate of a particular region of the country.  This chamber has been used to examine how different window glazes hold up to freeze thaw cycles similar to those experienced in the northeastern US, and will be used to simulate interior museum conditions for the cyanoacrylate aging study.
