Ok, could top of a Drescher's Bottle be used instead.
Sitting on a top of a flask, if tube is to big taking the suckbuck that takes bubbled in to water gas in to a trap, cut it, make it shorter or look
for a bigger capacity flask making sure volume of bubbler will fit in it not touching the tube that takes it there.

I’m pretty sure that is just a straight gas or vacuum takeoff adapter. Pretty standard item made in all common sizes. They are made in curved
versions too. There are several on eBay right now. I’m sure you can get them on Amazon also.

The one he’s using features a tubing connector at the top. Some have a ground glass joint at the top. Both types are easily found.

It looks like a thermometer adapter with a piece of glass tubing in it.
