Abstract

A configuration of mini-volume reaction receptacles (1, 16, 41) of which the receptacle housings (2, 17) each enclose an elongated chamber (3, 18, 42) of which the ends are connected to apertures (6, 7, 20, 22) formed in the receptacle housing. The receptacle housings have identical base surfaces and have a small height relative to the base surface, and are stacked on one another while their base surfaces are mutually aligned. At least one aperture of a receptacle housing communicates with at least one aperture of a vertically adjacent receptacle housing, as seen in the direction of stacking. The receptacles (1, 16, 41) are mechanically interlocked in a direction transverse to the direction of stacking and can be plugged one into another. Each receptacle housing defines at least one aperture (6, 7, 22) at its top side that is accessible to a pipette.
