Biological Indicator Gasket

Biological Indicator Gasket

The Biological Indicator Gasket

The great advantage of the self contained Biological Indicator over the traditional spore strip in glassine is the time saved when confirming spore kill. The indicator procedure to confirm positive or negative results requires only two days, versus the five to seven days required with a spore strip.
