Dialysis U-Tube Model

thingiverse

Create an osmosis model for demonstrating solute movement against gravity. The cost is approximately $15 if you have access to a laser cutter. Follow these steps: cut two stand and clamp parts; prepare the U-Tube by halving it (Eshopps AEO19005 is suitable); glue it into place using acrylic adhesive, heat forming may be needed; attach a dialysis strip with four 16mm M3 screws; fill each side with solutions of different solute concentrations.
