Hi Folks, looking for advice on a fume scrubber, I plan on having an upside down pvc funnel just over my reaction vessel which will be a 2000ml beaker with a small hose going out the side of my fume hood leading to three 500ml gas wash bottles packed with marbles and sodium hydroxide solution with an oil free 2.5 cfm vaccum pump at the end, my question is will this be enough to keep me safe from nox fumes? many thanks in advance for any answers, also how much sodium hydroxide should I add to each wash bottle?
