I would be surprised if they end up using pure copper for this purpose, but they might use Cu-alloys. Cu has been used for a long time as a lining in laboratory tissue culture incubators to prevent bacterial and fungal contamination. But for ease of cleaning, many modern incubators just use stainless steel. One exception are incubators produced by Sanyo which use a Cu-enriched stainless alloy. I don't know what percentage of Cu they use and whether it is as effective as pure Cu. But I've had one in my laboratory for the past 6 years and it looks/cleans just like stainless and appears to cut down on contamination. Here's an excerpt from Sanyo's literature: "Traditionally a copper lining can be used to control levels of contamination as it has germicidal properties that destroy any bacteria present. However, using copper often results in high levels of corrosion on the incubator walls. Sanyo has harnessed the decontamination properties of copper and combined them with the anti-corrosion properties of stainless steel to produce Incusafe, a reliable corrosion-free copper-alloy that keeps your chamber contamination free all day, every day, automatically." link: laboratorytalk.com
