Abstract
The subject invention pertains to an assay device suitable for use in testing samples for the presence of microorganisms. The assay device of the subject invention comprises a housing having two chambers therewithin, each chamber being partially defined by a first filter material and each having a liquid inlet, the device also comprising means for holding the first material in a first or second position, respectively, such that the chambers are either separate or in communication. This arrangement allows assays to be made more accurately, since material that is otherwise retained in the corners of the assay chamber can be simply washed away.
