自制微型加压过滤装置

Homemade Micro Pressure Filtration Device

利用玻璃滴管、脱脂棉以及洗耳球设计了一种简单高效的微型加压过滤装置,通过动态光散射仪和威尼尔压强计对过滤效果进行对比分析,发现该装置不仅过滤速度快,而且滤液中粒径分布小而窄。并提供了2则微型装置的应用案例:(1)加快获得“上层清液”,(2)实现沉淀转化的微型实验。

A simple and efficient miniature pressurized filtration device was designed using a glass dropper,skimmed cotton and an earwash ball.The filtration effect was analyzed by DLS test and Vernier manometer,finding that the device not only had fast filtration speed,but also realized small and narrow particle size distribution in the filtrate.Two applications of the micro device are also provided:accelerating the acquisition of the"upper clear liquor"and realizing the micro experiment of precipitation transformation.
