That's my thought also, but one of the staff members seems to think that it will vent "plasma" into the lab. I've tried to convince her that's not a thing and that what does get vented isn't a problem, but to no avail. So I was hoping to show her that I'm
not the only person who believes this...</div>

This is for any of you who have a plasma cleaner. What have you done about venting the "exhaust gases" from the device? </div>

We are moving our Fischione plasma cleaner into a new area sample prep area. In the old location, we were able to connect the exit port of the cleaner directly into the exhaust snorkel where a fume hood was once connected. In our new location, that will either
be impossible or will require a connection that spans many meters and passes through multiple walls. </div>

I am wondering how necessary people think it is to vent directly into some sort of building exhaust system. Any thoughts?</div>
