想问的是:培养基在冻干机内的时间需要挑战最长时间吗?比如说36小时
ISO 13408-3:2006(E)中也没有明确规定。
8.6.3 Process simulations
NOTE 1 Process simulations representing the aseptic processing of lyophilized products include extra difficulties associated with manipulative activities and human intervention.
NOTE 2 Concerns related to the introduction of microbiological media into a lyophilizer are minimized by a combination of working, cleaning, disinfection and sterilization methods, which make the use of liquid broth solutions in lyophilizers acceptable.
8.6.3.1 The process simulation procedure for lyophilized products shall represent the entire aseptic processing chain, including filling, transport, loading, chamber dwell, unloading and sealing, under specified, documented and justified conditions representing worst case operating parameters.
8.6.3.2 The lyophilizer process simulation shall duplicate as much of the lyophilization process, except freezing, as practical, including partial vacuum and duration as appropriate for the media. Boiling-over or actual freezing of the solution shall be avoided.
Factors to consider include, where applicable:
a) use of air instead of nitrogen;
b) maximum interval between sterilizations of the lyophilizer;
c) maximum period of time between sterilization and lyophilization;
d) quantitative aspects of worst-case situations.
NOTE An example is the number of trays loaded and duration of loading (chamber open to environment).
