What do I need to know about soxhlet thimbles?

Printer-friendly versionSend to friendI have only used cellulose thimbles, so I don't know what to say about glass or glass fiber thimbles. However, avoid anything that has binders or other adulterants that can be washed out of the thimble. High quality thimbles will advertise that they won't do this. As far as size is concerned, as long as the thimble matches the size of the soxhlet chamber or is a little smaller, you'll be fine.
