Abstract

Device for the determination of analytes having a sample application point, several separate sample withdrawal zones that are each connected with the sample application point by one capillary transport path and that have several test elements for the individual determination of analytes wherein a retardation zone is provided on at least one of the transport paths. Material for the capillary transport of a liquid sample defines a sample application zone and a plurality of sample withdrawal zones connected to said application zone by a like plurality of transport paths. At least one of said paths has a retardation zone which assures that liquid applied to said application zone arrives simultaneously at said withdrawal zones, regardless of the lengths of the paths.
