A sonicator is a device which cracks open cell walls by blasting 
them with shattering sound waves. They are very noisy - you should 
use ear protection when you run them!  I would think that most 
scientific supply houses would carry them (such as Fisher, Thomas, 
SP, etc.)

I assume that the evaporator that is referred to would be similar 
to those used in organic and biochemistry.  You might want to 
check with your chemistry department for more details.

You've got me on pressure reaction tubes though.  Perhaps you can 
call the author of the article?  Most scientists are quite happy 
to answer questions about their work.

Good luck.
