I'm just wondering if there is really a functional difference aside from the difference in size. Is one generally preferred over another?
If I buy a set of glassware, my aim would be to have the most popular joint size, so as to be compatible with other pieces I might find from private
sellers. I don't want to get 19/22 only to find that everyone and their mother on ebay or labx uses 24/40.
That being said, what is your preference?

I just buy what is compatible with what I already have: 24/40. It seems to be the most popular size in North America.

I bought 19/22 as I was familiar with it from school. Also I wanted to keep the size of my equipment down. The largest RB flask is 500 ml and the
smallest is 25mL.
This works fine if you just want to do a synthesis to verify that you can do it. But if you want to stock your reagent shelf the equipment size is a
little small. E.g., for making chloroform I would like to have a 1-liter or even a 2-liter flask.

If you're brewing nitric acid and such, you'll be handling large volumes and 24/40 is better.
As for me, in my organic chem labs, we use 14/20--and it's quite good for working on small scale (that is, 50 mL or less). Probably good for
orgainc synthesis, too...
Heh, but at work I came across a box of 24/40 columns--a good 18" long. I was surprised at how huge this popular standard taper really is.
