Step 12The Bubbler
The bubbler can be made in any number of ways, for large gas flow rates I use an old water filter housing that I've modified.
The nylon sight tube is a necessary feature and I made mine in the top cap to indicate the highest water level. Safety dictates that the smaller the volume above the water, the smaller the explosion when you get a flashback.
This device has taken care of a few flashbacks without any problems
Other embodiments of bubblers include but are not limited to 20mm clear vinyl tube as in the pic below, and also Sch 40 PVC pipe with end caps can do serviceable duty as a bubbler.
