I am considering purchasing an "Osmosis and Diffusion Demonstration
Model" from Ward's http://wardsci.com/product.asp?pn=148313 . Has
anyone had any luck with this gadget? Is it any better than struggling
with thistle tubes or dialysis bags to demonstrate osmotic pressure?
I am also searching for a good potometer setup, preferably with a
stopcock so students can reuse the apparatus without taking it all apart
repeatedly.
Thanks,
