Sample focuser for solid-phase analytical device.

摘要

An improved analytical device useful in solid-phase binding assays to determine the presence or amount of an analyte in a test sample. The device comprises a focuser which directs test sample onto the reactive surface of a solid-phase binding assay device. The focuser can have any arrangement of passages to correspond to the configuration of the reactive surface present on a solid-phase binding assay device. The focuser can also include a filter means for filtration of a test sample prior to contacting the reactive area of a solid phase binding assay device.
