Title: Measurement of specimen
Inventor: TAKAYAMA HIDETO
IPC: G01N33/543
Filed: 1991-08-30
Abstract: PURPOSE:To facilitate judgment by making the specific gravity of a carrier particle used in reaction heavy or light. CONSTITUTION:A conical through-hole 2a uniformly increased in its diameter downwardly is formed in a substrate 1. The size of the opening at the upper end part of the substrate is smaller than the diameter R of carrier particles F, and that of the opening at the lower end part thereof is set so as to permit flocculated matter G to pass. The carrier particles F whose specific gravity is lighter than that of the liquid of a specimen is sensitized with immunologically active substance and, when the reagent dispersed in a liquid medium whose principal ingredient is water is mixed with the specimen, reaction is generated to form the flocculated matter G from a plurality of the immunologically active substances and the carrier particles F. The reaction solution L is injected through the upper opening part 3 to fill the hole 2a. At this time, since the specific gravity of the carrier particles F is lighter than that of the liquid, the carrier particles F or the flocculated matters G move up in the reaction solution. The carrier particles can move hear the top part of the conical hole because of its small diameter but the flocculated matters G are trapped on the way because of its size to become impossible to move.
