WebDialysis tubing is a semi-permeable membrane, usually made of cellulose acetate. It is used in dialysis, a process which involves the removal of very small molecular weight solutes from a solution, along with equilibrating the solution in a new buffer. This can also be useful for … Web89 Word(s) A plasma membrane is the membrane that is found is cells that sepertates the inside of the cell from the outside. This is similar to the dialysis tubing because there was the solution inside the tube and water+IKI on the outside and they were seperated. The difference between them is that in the dialysis tube overtime both solution merged …
