what is the difference between a crystalloid and a colloid solution
Volume expander There are two main types of volume expanders: crystalloids and colloids. Crystalloids are aqueous solutions of mineral salts or other water-soluble molecules. Colloids contain larger insoluble molecules, such as gelatin; blood itself is a colloid. There is no evidence that colloids are better than crystalloids in those who have had trauma, burns or surgery and as they are more expensive their use is not recommended.[1]
MDMA "Molly", short for 'molecule', was recognized as a slang term for crystalline or powder MDMA in the 2000s.[158][159]

Vapor–liquid separator For the common variety, gravity is utilized in a vertical vessel to cause the liquid to settle to the bottom of the vessel, where it is withdrawn.[1][2][3][4]
