Q: What is the tube size? My 1/4" ID tube will not fit.

Try 5/16" ID Silicone tubing. 3/8" Tygon might work as well.

Q: is anyone positive (Not "pretty sure") what size stopper works with this flask?

The flask opening is one and three-eighths inch in diameter. Do a internet search for standard stopper sizes. A stopper that is one and one-half inches in diameter at the widest end should be adequate.

I'm pretty sure it was a size 10
