擠出原理
Extrusion Principle
脂質(zhì)體擠出的原理在于，通過一定的擠出動力源將脂質(zhì)體樣品粒子進行擠壓，使其在一定壓力條件下通過PC濾膜， 此壓力作為粒子過膜過程中的剪切力可使其達到粒徑控制的效果。不論形態(tài)、大小和分布都可得到極大改善。
The principle of liposome extrusion is that the particles of liposome sample are extruded by a certain extrusion power source to pass through the PC membrane under a certain pressure. The pressure acts as the shear force in the process of the particles passing through the membrane, which can achieve the effect of particle size control. The shape, size and distribubtion can be greatly improved.
