Using the Size 29 Joint
A standard taper joint is ground so that any inner joint of the same size fits it, which is how the flask is connected to a condenser, adapter or stopper of matching size without corks. Wipe the ground surfaces clean before assembly, as grit can make a joint stick. Because the base is round, hold the flask with a clamp at the neck or set it in a ring support rather than standing it on the bench.
