This clear polypropylene test tube top serves as an excellent barrier against the contents of the tubes. While the exterior grooves would serve to hold identification labels, the grooves inside the cap tighten the fitting on the tube. The combination would become leakproof because of the built-in seal ring that would sit in the tube.
