Liposome Preparation - Avanti® Polar Lipids | Sigma-Aldrich

Properties of lipid formulations can vary depending on the composition (cationic, anionic, neutral lipid species), however, the same preparation method can be used for all lipid vesicles regardless of composition. The general elements of the procedure involve preparation of the lipid for hydration, hydration with agitation, and sizing to a homogeneous distribution of vesicles.

Tricks of the Trade for Removing High Boiling Point Solvents

When evaporating a volatile solvent such as methanol you will probably be removing solvent with a boiling point (at the pressure present in the chamber) of -20oC or less. This requires a very cold condenser to capture the vapour. But with HBP solvents, the solvent 's BP may be as high as +25oC (or more). This presents an entirely different
