BIOLOGICAL INDICATOR INSTRUCTIONS -- NAS-152
Certifi cate of Analysis
PROCESS EVALUATION
'Place biological indicators in Iocations pleviously deterrnined to be the most diffrcult to sterilize.
Aleas experiencing rninimal gas flow or poor gas distribution include enclosure comers, areas in and
atouud equiptnent, and locations among disposable rnate¡ials to be used in the enclosure. Note that
the inoculated side ofthe carrier faces the prìnted label on the Tyvek pouch, therefore the printed
side should face outward during a process cycle.
