Abstract
Prezenta inventie se refera la un dispozitiv pentru dozare si transfer de lichide în cîte o celula receptoare, în vederea efectuarii unor analize, spre exemplu, biologice, celule receptoare facînd parte din cadrul unui ansamblu rotativ care are forma unei cutii cu axa verticala, în interiorul careia se afla o serie de compartimente si canale, inclusiv compartimente de alimentare cu lichid, compartimente de dozare, de prea plin si de primire a lichidului dozat. Dispozitivul pentru transferul unei doze determinate dintr-un esantion de lichid într-un microspatiu de analiza este prevazut cu un orificiu de trecere a lichidului, fiind capilar, orificiile delimiteaza pentru compartimentul ce are functia de camera de masura, adica de dozare, un volum determinat, iar canalul de scurgere are în vecinatatea orificiului capilar de asemenea, o deviatie care este de fapt un canal de legatura cu o camera de prea plin. Orificiul de intrare, este situat în apropierea unui perete radial care delimiteaza compartimentul de alimentare, orificiul capilar fiind la rîndul sau situat în vecinatatea celui de al doilea perete radial care delimiteaza compartimentul de alimentare, iar deviatia fiind situata în raport cu canalul de scurgere pe aceeasi parte ca si compartimentul cu functia de camera de masura, adica de dozare.
