I'm looking for a certain type of plastic container (around 2-3 gallons) that has a spigot on the bottom and allows you to drain liquid using gravity. I used to see them a lot in the Navy used for cleaning fluids but can't figure out what to search for to find them.
I'm ultimately looking for something I can put liquid into and attach surgical tubing to the "drain" or "spigot" and has an on/off valve.
Does anyone know what these are called or where I can find them?
