ABSTRACT:
There is disclosed an evaporation cover that is useful to cover two types of test elements having different sample wetting locations, namely potentiometric types and colorimetric types. Both are accommodated by constructing enough of the flat sealing portion of the undersurface so as to sealingly cover the wetted area of the colorimetric type, and by providing on the cover, means for camming the cover away from a test element that is being loaded under the cover.
