Good afternoon Rachel,
Our labs utilize 5-gal carboy that we source directly from a local vendor. This reusable cap is then installed in-line to capture vapors and avoid splashes/spills while still in use. The cost does not include plugs or Inserts for different connections.
I'm not responsible for this program but can get answers questions or connect you with our team.
Cheers,
-P

Subject: [DCHAS-L] LC with Acetonitrile Ventilation
Hello!
We are hoping to do some work with the LC this summer using acetonitrile but are concerned about ventilation of the fumes. Our waste currently runs to a bottle that has a closed funnel. Do labs typically have their LC waste container in a fume hood for ventilation? Our LC is currently in a fairly small room that has one large vent in the ceiling. Any thoughts or recommendations would be greatly appreciated!
Thank you,
