It better be ab air-tight set up because EtO's PEL-TWA is 1 ppm. And then the DEP gets into the act at the fume hood stack because there are air quality limits as well. Monona

Hello,
Does anyone have any researchers working with an ethylene oxide/THF solution? This can be purchased from Sigma. We have a researcher that is hoping to make their own by condensing ethylene oxide in THF to make a fresh solution. They are
working through the process on paper right now, trying to consider all risk, and I was curious if anyone else has come across a similar situation that they would be willing to share.
Thanks,
Stephanie
