Qualification in the inspection system shall be done with reference to particulates during the visible range of a kind That may emanate within the production or filling approach. Each and every container whose contents exhibits evidence of visible particulates shall be turned down. The inspection for obvious particulates may perhaps occur when inspecting for other critical defects, which include cracked or faulty containers or seals, or when characterizing the appearance of a lyophilized item.
The endotoxins Restrict for USP/BP sterile WFI is just 0.25 EU/ml; for that reason, sterile WFI might incorporate detectable endotoxins and become unsuitable to be used. Use Qualified LRW to produce dilutions of expectations, and to organize constructive controls.
