Principle of coaxial-air-driven bead generator

生产大多数涉及活细胞和生物活性物质需要的微胶囊（直径<1毫米），并具有严格控制生物材料活性的功能。营养物质扩散的限制主要决定于水凝胶囊。本产品生产的微胶囊具有方便可控的特点，是利用静电发生器产生的。仪器的基本原理是通过同轴气流，使物质经针尖产生的小珠形成微胶囊。该仪器是专门生产大小在400微米左右的胶囊。并且本装置具有易于清洗和消毒，使用方便的特点。

In most applications involving immobilisation of living cells or other biological materials the bead size needs to be small (<1 mm) and carefully controlled. The reason is mostly limitations of nutrient-diffusion into the hydrogel beads. An easy way for production of small alginate beads in a controllable manner is the use of a coaxial-air-flow bead generator. The basic princi-ple of the instrument is the use of a coaxial air stream which pulls droplets from a needle tip into the gelling bath. The Nisco instrument is designed for research uses production of smaller quantities of spherical alginate beads ranging in size down to around 400 µm.
