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

    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.
