Abstract
L'invention est relative à de nouveaux procédés et dispositifs pour l'analyse d'échantillons de très faibles volumes. Le procédé consiste à effectuer les prélèvements de réactifs par capillarité à l'extrémité de tiges fines, puis à récupérer les prélèvements par centrifugation, les réactifs étant projetés au fond d'un même récipient. Le dispositif comprend des éléments pour le prélèvement, associés à un récipient pouvant être centrifugé. Le procédé et le dispositif sont particulièrement utiles pour les micro-analyses enzymatiques.
