Solid Carbon Dioxide or CO2, at atmospheric pressure, changes directly from solid to gas and forms a very convenient low temperature coolant, leading to its wide use in laboratories and industry.
CO2 has a steady temperature of -78°C. This otherwise desirable property means that, if its stored in in delivery packaging, it has a short life particularly if in pellet form or if blocks are broken into fragments. Storage in a refrigerator or even a freezer is of little help because of their higher operating temperatures.
Our storage chests are specifically designed for the storage of solid Carbon Dioxide, they require no power supply and can be used as a low temperature, low cost cabinet for preserving thermally unstable materials or for low temperature environmental testing.
