A self-resealing container cap configured to make a closing engagement with a container and a septum of elastomeric material supported in an opening defined by the cap periphery. The septum is puncturable by a blunt tip of an instrument such as a disposable plastic pipetter tip or a single use plastic laboratory transfer pipette having a tip width substantially greater than the thickness of a central portion of the septum. The septum is further configured to be substantially self-resealing against significant leakage of specimen liquid through the septum following withdrawal of the blunt tip from the punctured septum. |
