Function:
Dialysis tubing is actually a semi-permeable membrane when used in water. Experiments illustrating osmosis and pressure gradients across a membrane use dialysis tubing. This tubing usually comes in rolls and when wet, will open up into a cylindrical tube that can be tied off at the ends. The tubing can also be fitted over a thistle tube for such experiments.
