Beschreibung
Zusammenfassung:	Disclosed is an improved device for performing agglutination reactions having at least one chamber (25) having a proximate zone (6) and a distal zone (7), in which chamber (25) agglutination reactions can be performed. The improvement comprises utilization in the device of means for controlling overall rate of liquid flow through the chamber (25), the means comprising a layer (2) of liquid absorbent material selectively impregnated with a substance to form an impregnated region (26) and a non-impregnated region (4) wherein the non-impregnated region (4) is liquid absorbent and the impregnated region (26) is liquid-occlusive. The non-impregnated region (4) is in liquid communication with the distal zone (7) of the chamber (25). Dispositif amélioré permettant de procéder à des réactions d'agglutination et comportant au moins une chambre (25) présentant une zone proximale (6) et une zone distale (7), les réactions d'agglutination intervenant dans ladite chambre (25). L'amélioration comprend l'utilisation dans le dispositif d'un moyen de régulation de la vitesse globale de l'écoulement de liquide à travers ladite chambre (25), le moyen comprenant une couche (2) de matière absorbant du liquide sélectivement imprégnée d'une substance afin de former une région imprégnée (26) ainsi qu'une région non imprégnée (4), ladite région non imprégnée (4) absorbant le liquide et ladite région imprégnée (26) arrêtant le liquide. Ladite région non imprégnée (4) est en communication fluide avec la zone distale (7) de la chambre (25).
