ABSTRACT:
A reagent format having an inverse funnel shaped body which includes a central capillary tube that opens into a flow passageway. The flow passageway is formed, in part, by providing a recessed flow surface at one end of the inverse funnel shaped body which is surrounded by a stepped shoulder. A test substrate, such as reagent film, is secured to the shoulder so as to form one surface of the flow passageway. The device is suitable for both drawing and spreading a fluid test sample onto a test substrate in one step. Additionally, one or more small diameter vent passageways open into the flow passage to allow for air to excape when fluid is drawn into the flow passage through a capillary action. The pen-shaped body is also formed of a clear or translucent material such that the flow of the test fluid can be observed by the user.
