The Biological Indicator Gasket
The great advantage of a self contained biological indicator over the traditional spore strip in glassine is the time saved when confirming spore kill. Results are easily obtained in only 24 hours (versus the 5 to 7 days required with a spore strip). The indicator procedure to confirm positive or negative results requires only two days, versus the five to seven days required with a spore strip.
