各位TX,最近在看欧盟新无菌附录的征求意见稿(2017),在隔离器这章有点晕,哪位TX明白的不吝指导
5.18 For RABS, the background environment should meet grade B. For open RABS, or where doors may be very rarely opened during processing, and studies should be performed to demonstrate the absence of air ingress.
5.19 For open, positive pressure isolators or closed isolators with decontamination by a sporicidal agent, the surrounding area should correspond to a minimum of grade D.
对于RABS,尤其是O-RABS,按照以前的概念很好理解,但对于isolator,所谓“正压开放隔离器”不太理解,也没见过,而且开放正压,也可以放在D级背景?
