Abstract
Microcentrifuge tube having a container having a round opening and a frictionally seated lid hingedly connected by a fixed-hinge to the container, the lid having an upper lid surface and being sized and shaped to cover and seal the opening to maintain the inside of the tube free of any contaminant. The lid has a lid extension extending upwardly from the lid surface and outwardly away from the hinge in such a manner which allows the lid to be unseated and moved from the opening of the container when mechanical pressure by a user's finger is applied to the lid. The lid further has a guard portion extending downward from a portion of the lid and configured and arranged adjacent the container to act as a finger guard to prevent a user's finger contacting the container.
