Abstract
Apparatus and washing and extracting head for an apparatus designed to wash microplates. The head is mobile above the microplate(s) in treating position and comprises an alignment of dispensing needles or tubes and suction needles or tubes associated in pairs, the number of the two types of needle pairs being equal to the number of wells per column or per row and the spacing between two adjacent pairs being equal to the spacing between two adjacent wells of the same column or row. The suction needles, and the parts of the consecutive suction and/or recovery circuit, have a passage cross sectional diameter not less than the largest transverse dimension of the sample supports present in the wells and the head comprises or co-operates with elements retaining the microplate to be washed or preventing it from being lifted, at least during the suction extraction phase.
