Abstract

Le mélange, les réactions physiques et/ou chimiques et la séparation sont des étapes fondamentales dans la recherche et le diagnostic biologiques. Notamment la recherche requiert des systèmes de laboratoires spécifiques aux tâches n'étant pas disponibles dans le commerce en raison de leur faible diffusion et de leur utilisation spécifique. Face à l'absence de ces systèmes, la résolution de ces tâches nécessite d'improviser au moyen des récipients, filtres, centrifugeuses etc. disponibles. L'invention vise à proposer un système d'unités fonctionnelles pouvant être assemblées en fonction des processus imposés par les tâches. Le système selon l'invention est constitué d'unités fonctionnelles pouvant être combinées librement, et se compose de cylindres de mélange, de dispositifs de séparation et d'une unité de connexion à régulation du flux, de préférence conçue en tant qu'unité à vide. Le système est conçu de telle manière que les unités fonctionnelles sont connectées, au moyen de connexions par enfichage, dans un ordre quelconque et dans une quantité d'unités fonctionnelles quelconque, de manière à former un système de traitement d'échantillons fermé.
