WebDialysis is the separation of smaller molecules from larger molecules in solution by selective diffusion through a semipermeable membrane. Dialysis tubing will be used in this laboratory to simulate a cell membrane. It is made of selectively permeable cellulose tubing perforated with microscopic pores. The pores are small enough for the tubing ... Dialysis occurs throughout nature and the principles of dialysis have been exploited by humans for thousands of years using natural animal or plant-based membranes. The term dialysis was first routinely used for scientific or medical purposes in the late 1800s and early 1900s, pioneered by the work of Thomas Graham. The first mass-produced man-made membranes suitable for dialysis were not available until the 1930s, based on materials used in the food packaging industry suc…
