Feb 01, 2015 The interest of the pilot plant is to translate the preparation at laboratory scale to semi-industrial scale, but also to make the entire process (including the evaporation of ethanol) on the same installation. This avoids eventual contamination related to transfer of the preparation for ethanol evaporation using a rotary evaporator. 2.

Feb 22, 2013 Liposomes, sphere-shaped vesicles consisting of one or more phospholipid bilayers, were first described in the mid-60s. Today, they are a very useful reproduction, reagent, and tool in various scientific disciplines, including mathematics and theoretical physics, biophysics, chemistry, colloid science, biochemistry, and biology. Since then, liposomes have …

For high transition lipids, this is easily accomplished by transferring the lipid suspension to a round bottom flask and placing the flask on a rotory evaporation system without a vacuum. Spinning the round bottom flask in the warm water bath maintained at a temperature above the Tc of the lipid suspension allows the lipid to hydrate in its fluid phase with adequate agitation.

How is Product L4395, Liposome Kit, used? The Liposomes of a large multilamellar structure type are the most widely used. They can be prepared using Sigma liposome mixtures by concentrating an organic solvent solution of lipids to a thin film on the walls of a container such as by rotary evaporation or by drying in glass with a stream of nitrogen gas.

Liposome properties such as size, polydispersity index (PDI), and charge were screened before and after ethanol evaporation. Results: Only rotary evaporator (at constant speed and room temperature for 2 h) removed all of the ethanol content, with a final drug entrapment efficiency (EE) of 29.44 6.77%. This was higher than a conventional method.
