We normally used 4 liter narrow mouth bottles, recycled from laboratory reagents such as acids and bases, for general laboratory wastes. That was for economic reasons.  We did place large wide stem plastic funnels on top of the bottles to reduce spills that would contaminate the exterior of the waste bottles.

Subject: [DCHAS-L] Lab Waste accumulation bottle preference

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.
