A liquid spreading device and a method of spreading a liquid by means of this spreading device. The spreading device (10) includes opposed surfaces (16, 18) providing a capillary flow zone. Each surface (14, 16) includes means (42, 44) for directing flow along predetermined paths and at least one surface (16) includes means (26) to permit liquid introduction between the surfaces (16, 18. At least a portion of the paths of one surface form a positive angle ( alpha ) with respect to the paths of the directly opposing portion of the other surface, whereby controlled multidirectional flow of liquid introduced between the surfaces occurs with a predetermined peripheral configuration. Also disclosed are methods of analyzing a liquid and test elements for them which include the spreading device and the method of spreading the liquid. |
