A while back I was a visitor (For 1 day) to a company that assembled vaporisers. Their research chemist took us to their lab and showed us some experiments they were doing on o-rings. They had O-rings suspended in glass jars above anaethetic agents to see how the o-rings reacted to different agents over time. It was a bit of an eye opener to see how some o-rings were unaffected, some had expanded to twice their original size, some had disintegrated entirely ect. I have no experience with the materials in these vaporisers, but just be aware, different agents do react differently with the materials they come into contact with. My question would be, is all the materials in a Isoflurane vaporisers suitable to be exposed to Halothane?
