Abstract
The present invention provides a device for activating a self-contained biological indicator. The biological indicator includes a casing, an ampule having a growth-promoting medium disposed therein and microorganisms. The ampule and microorganisms are disposed within the casing. The device is comprised of a first lever arm having a cavity formed therein. The cavity is dimensioned to receive a biological indicator. A second lever arm has a protrusion extending from a surface thereof and is moveable relative to the first lever arm to deform a casing of the biological indicator thereby fracturing an ampule in the casing and exposing microorganisms in the casing to a growth-promoting medium in the ampule of the biological indicator.
