What the 14/29 Size Means
The first figure is the width of the joint at its wide end, about 14 mm, and the second is the length of the joint, 29 mm. A 14/29 neck mates only with fittings carrying the same marking, so check it before adding a condenser or adaptor.
Handling the Flask
A round bottom will not stand on the bench by itself, so hold the flask in a clamp at the neck or rest it on a cork ring. Fill it no more than about half full for heating, add anti-bumping granules before boiling, and never heat it with the system closed: the apparatus must stay open to the air through the condenser.
