    (b) a handling-piece connected to said test component;

    (c) an accessory component having an accessory solid surface which is of substantially complementary shape to said test component surface and removably fixed in slightly spaced apart relationship therewith, to define therebetween a containing space for retaining a liquid sample;

    (d) a means for removably fixing said accessory component (c) to said handling-piece (b) or to said test component (a) so that said accessory component (c) is maintained in said slightly spaced apart relationship with said test component (a) and so that said accessory component (c) remains fixed to said handling-piece (b) or said test component (a) when said device is held and moved by said handling-piece (b); and

    (e) at least one aperture through which a sample of liquid from an external source enters said space when said device is held in contact with said source, said sample being retained in contact with said test component surface, said device further comprising;

    (f) a support component, and(g) a means for interlocking said support component (f) with said accessory component (c) to facilitate removal of said test component (a) from said accessory component (c) without the user handling either said test component (a) or said accessory component (c) directly.
