1. An analytical device for determining the presence and/or concentration of an analyte in a sample liquid, comprising:
- a) a hollow casing;
b) a bibulous sample liquid receiving member at or adjacent to a first extremity of said casing, said receiving member providing means for collecting sample liquid and transporting collected sample liquid into said casing;
c) means within said casing for selectively capturing said analyte in said collected sample liquid;
d) window means in said casing at a location remote from said first extremity of said casing, said window means enabling detection of said analyte to be effected from outside said casing; and
e) a single cover means engageable with said casing to enclose said bibulous sample receiving member and releasably engageable with said casing to enclose said window means, but not engageable with said casing to enclose both of said bibulous sample receiving member and said window means simultaneously.
