Upon request, EH&S/Haz Waste Management Group, provides 2.5 and 5 gallon carboys for waste collection.  These carboys have a large (2.5"?) opening on the top for the addition of waste.  If an individual lab doesn't generate enough to fill a carboy within the regulatory accumulation period, the labs typically use recycled/reclaimed 4 liter glass bottles for waste collection.  EH&S doesn't provide the 4 liter bottles.


Hope this helps,

I'm getting ready to order some waste accumulation bottles for our laboratories and wonder if there is a practical reason to have narrow mouth bottles rather than wide mouth bottles. It seems like the wide mouth bottles would eliminate the need for a funnel during the filling process and lead to less exterior contamination of the waste bottle. However, standard practice appears to be narrow mouth bottles and I wonder if this is due to a specific practical reason or inertia?

Thanks for any thoughts on this.
