Here's another bottle from McMaster-Carr. This one is #1044K4. It is also 500 cc's. It has an aluminum spout with a screw cap. The hole in the spout is small, so I cut off the very tip, and ran a drill through it. We used it all day today with no problems. As a bonus, the bottle is very soft and pliable. This one is $9.15. It is a better choice unless you need a bottle with a spout that can be soldered.
