Ø Name: NLI Liposome Extruder
Ø Location: Rm. 801, SCM
Ø Technician: Dr. Li Min Zhou (lmzhou@hkbu.edu.hk)
Ø Description: The liposome Extruder is designed to generate homogeneous populations of unilamellar vesicles
(liposomes) without the need for solvents or detergents. Extrusion is a quick and simple one-step procedure that
produces liposomes by forcing aqueous suspensions of lipid through polycarbonate filters with defined pore size. It is
relatively gentle, exposing the formulation to moderate pressures (100 – 700 psi) at controlled temperatures which
contrasts with homogenization where temperature may fluctuate, and pressures often exceed 18,000 psi. The LIPEX
Extruder offers anumber of advantages over alternative lipid manufacturing strategies.
