Product Description


Strip is a conventional spore strip biological indicator for monitoring steam, low-temperature steam formaldehyde, ethylene oxide, and radiation industrial sterilization processes. Strip contains bacterial spores on a paper carrier sealed within a convenient, peel-open glassine envelope. To use a Strip, place the glassine envelope in a product or product package, then place the “inoculated package” in a sterilizer and process normally. Upon removal from the sterilizer, send the inoculated package to the microbiology laboratory where the Strip* is to be aseptically transferred to soybean casein digest culture medium and incubated at the appropriate temperature for 7 days.
