What is Osmosis?
The movement of solvent molecules through a semi-permeable membrane from a region of lower solute concentration to higher solute concentration. Osmotic pressure is the pressure needed to prevent this flow. Osmosis is vital in biological systems for cell volume regulation.

Hypertonic IV solutions cause hemolysis of red blood cells — must precisely control osmolarity of intravenous fluids. Reverse osmosis membranes require regular sanitization to prevent bacterial biofilm growth. Osmotic pressure in sealed containers with hygroscopic materials can build up causing cont…
