A lid includes a top having a cover receiving portion having a first aperture and a second aperture formed therein, a hinge positioned about a center of the cover receiving portion such that the first aperture is on one side of the hinge and the second aperture is on an opposite side of the hinge, and a cover having two directly opposing sidewalls rotatably attached to the cover receiving portion via the hinge. Each sidewall includes a protrusion extending therefrom shaped to fit within one of the first and second apertures. The cover pivots relative to the cover receiving portion so as to engage either the first aperture or the second aperture, and when the protrusion on one sidewall of the cover is pivoted towards the first aperture, the protrusion on the other sidewall simultaneously pivots away from the second aperture.

A test sample card is produced from a mold machined in accordance with an electronic discharge machining (EDM) process, with a resulting finely textured surface of the mold left intact. The mold produces a test sample card that has an even finely textured surface which improves the adhesion of a membrane to the card surface. The card is better able to withstand prolonged incubation periods without separation of the adhesive membrane from the card surface, as compared to prior art cards.
