Claim 1

In a container having a sidewall, a bottom wall joined to said sidewall at a junction point, and a reagent deposited on an inside surface of said bottom wall; the improvement wherein said container further includes absorber means extending from said bottom wall at or below said junction point for absorbing shock, said absorber means having a length and thickness sufficient, when said container is dropped bottom wall first at a distance of 68.6 cm onto a hard surface with a container weight of 1.716 g, to prevent a dried reagent weighing 0.016 g deposited onto said inside surface from being dislodged, and wherein said container and said absorber means comprise a plastic that is sufficiently flexible as to allow said sidewall adjacent said bottom wall to be squeezed by finger pressure.
