I purchased dialysis tubing from carolina medical supplies with a molecular weight cutoff of 12,000 to 14,000 MW. I've been using a sugar solution to demonstrate osmosis but I've noticed that if I leave it alone for an hour or two the sugar begins to leak through the membrane. Is there anything else I could use instead of sugar that wouldn't leach out while still being a good solute to demonstrate osmosis and osmotic pressure?
