Osmosis Set
This set contains a glass thistle tube and a 12" piece of dialysis tubing. The materials are sufficient to do up to three osmosis or diffusion experiments. Instructions are included for one omosis and one diffusion experiment. You provide corn syrup and corn starch for the experiments.
The dialysis tubing is selectively permeable regenerated cellulose. Pores in the membrane permit passage of water, most ions, and small molecules. Particles with high molecular weight, like starch, polysaccharides, fats, and protein are restricted.

Very satisfiedReviewed By: Gavin Hudson I'm very happy to have the osmosis kit from HomeScienceTools. I couldn't find osmosis lab material in South Korea, where I live. If there were constructive feedback, it would be that I wish HomeScienceTools could ship internationally.

Osmosis SetReviewed By: Virgil Gibbs This is a neat kit. The kids thought it was fun to see the starch turn black when the iodine was pulled into the thistle tube. A good experiment for discovering osmosis.
