A cap assembly caps a sealed vial having a sealed flat top surface defining a top diameter and a side surface extending down therefrom. The cap assembly includes a cap top defining an outer surface and an inner surface. The cap top defines a cap diameter which is slightly larger than the top diameter. The cap top also defines a cap top periphery. A side rim extends out from the cap top about the cap top periphery to engage the side surface of the sealed vial. The side rim includes an inner surface. A pad is fixedly secured to the inner surface of the cap top. The pad is fabricated from an absorbent material, wherein the absorbent material is saturated with a liquid disinfectant 54 to disinfect the sealed top surface when the cap assembly covers the sealed vial in a manner such that the pad contacts the sealed flat top surface.
