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.

Washing and extracting head for microplate washing appliance and corresponding appliance

Device for mounting an elongated element with axial clamping, includes a body forming a support base whereon are fixed a stop part including a first support element for one end of the elongated element and a retaining part, the parts being axially separated, a removable support block comprising a through passage for receiving the elongated element and capable of being wedged between the retaining part and stop part, and a mobile part including a second support element for the other end of the elongated element, the mobile part is secured in articulation to two link rods mounted at their opposite ends, potentially rotatable, on two eccentrics mounted potentially rotatable on the body and rigidly assembled to a pivoting cover provided with a member or zone for gripping or maneuvering, the cover or lid substantially covering the assembly of the parts and the elements when it is folded down.
