在普通制剂配制过程中,我们采用了微孔滤膜滤器滤过法(以定性滤纸代替微孔滤膜),收到较好的效果,既提高了工作效率,又提高了制剂质量。现简介如下:一、密闭式滤过架的制作:此架为木质材料,各层均衬以塑料板,安装内径为100mm的微孔滤膜滤器一只;底层可放1万ml龙头瓶4只,中间两层及上层可各放5千m1龙头瓶6只,供存放成品。(见附图)二、操作过程:配制量较大(如5千~1万ml)时,以标有刻度(经容量瓶校准)的龙
In the preparation of ordinary formulations, we use a microporous membrane filter filtration (qualitative filter paper instead of microporous membrane), received good results, both to improve work efficiency, but also improve the quality of preparation. The brief introduction is as follows: First, the production of confined filter rack: This rack is made of wood, the layers are lined with plastic plates, the installation of a diameter of 100mm microporous membrane filter a; bottom can put 10,000 ml faucet bottle 4 Only, the middle two floors and the upper can be put 5 thousand m1 faucet bottle 6, for the storage of finished products. (See photo) Second, the operation process: Preparation of a large amount (such as 5 1000 ~ 1 000 ml), marked with a scale (by the volumetric flask calibration) of the dragon
