Expansion Adapters
Product Code : JA-LAOK-1557
Expansion Adapters (product code JA-LAOK-1557) join two pieces of jointed glassware whose ground-glass joints are different sizes. Each expansion adapter has a cone that fits the smaller socket of a flask or other apparatus, and a larger socket that accepts the cone of the next component, such as a condenser, still head or dropping funnel. Eleven cone and socket pairs are listed, from B10/B14 up to B29/B40, for college, research and school chemistry laboratories.
Specifications
Each expansion adapter is a single glass piece with a ground-glass cone at one end and a larger ground-glass socket at the other. It is listed in 11 cone and socket pairs, so a buyer chooses the pair that matches the two joints being connected in the set-up.

Applications of the expansion adapter
An expansion adapter is used when a flask has a smaller joint than the apparatus that has to sit on it, so that existing glassware can be combined without buying new flasks or condensers.
- Fitting a condenser or still head with a larger cone onto a flask with a smaller socket
- Combining glassware bought at different times with different joint sizes
- Distillation, reflux and extraction assemblies in B.Sc. and M.Sc. practicals
- Keeping a mixed set of jointed glassware usable in teaching and research laboratories

Frequently asked questions
Which size pairs are available?
Eleven cone and socket pairs are listed: B10/B14, B14/B19, B14/B24, B19/B24, B14/B29, B19/B29, B24/B29, B19/B34, B24/B34, B29/B34 and B29/B40.
How do I choose the right pair?
Match the cone to the socket size on the lower piece, usually the flask, and the socket to the cone size of the apparatus that will sit on top.
Is there an adapter for going from a larger joint to a smaller one?
Yes. Reduction adapters do the opposite job and are listed in the same adapter range.
