在注射剂生产过程中，配制工艺常要求使用活性碳以去除热原或脱色等，即需在洁净区内使用活性碳。这个过程或多或少都会对洁净区造成一定的污染，如操作不当，则会使洁净区受到严重污染，加重净化系统的负荷，缩短高效过滤器的使用寿命，并导致注射剂成品中出现黑点，澄明度不 In the injection production process, the preparation process often requires the use of activated carbon to remove pyrogen or decolorization, which requires the use of activated carbon in the clean area. This process more or less will cause some pollution to the clean area, such as improper operation, it will make the clean area seriously polluted, increasing the load on the purification system, shorten the life of high efficiency filter and lead to black spots in the finished injection , Clarity is not
