Dear Division Members, I'm sure most of you are in San Francisco attending the national meeting, but I'd like to get your input on this topic... We have a biogeochemistry lab that uses open 4 L beakers of nitric and hydrochloric acid on hotplates in a fume hood to clean the sample jars they use. Does anyone at your institution do similar work? Is there any pre-made glassware designed for this use that captures these emissions? Of course I am prepared to encourage their use of a round bottom flask with reflux condenser, but I am looking for other suggestions.
