Abstract
Abstract 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
41 words
A sample focuser suitable for use with a solid-phase assay device comprising side walls and a base for containing a sample material and having passage means for directing said sample to an analyte reaction site present on said solid-phase assay device.
Claim 2
Dependent Claim
41 words
A sample focuser suitable for use with a solid-phase assay device comprising side walls and a base for containing a sample material and having passage means for directing said sample to an analyte reaction site present on said solid-phase assay device.
Claim 3
Dependent Claim
29 words
