Notes: 

1. Used to connect different sizes of glassware via expanding or reducing the joint size
2. Expansion means going from a smaller joint (socket) to a larger joint (cone)
3. Reduction means the opposite
4. ie The Expansion Adapter 24 ---> 29  will have a 24/29 cone and a 29/32 socket
5. ie The Reduction Adapter 34----> 29 will have a 34/33 cone and a 29/32 socket
