Abstract: A connector for providing both a fluidic and electrical connection is disclosed, said connector having a proximal end, a distal end and an elongated body in between, characterized in that the elongated body has an inner cavity spanning throughout its length, and the distal end comprises: a) an inner body portion comprising a first inner electrical contact and b) an outer body portion comprising a second outer electrical contact having a spring element. The connector is easily adaptable to many kind of fluidic actuators and particularly to pipette instruments usually found in laboratory practice and developed to adapt fluidic actuators and pipette instalments to work according to the Coulter principle in every working condition, in particular to adapt the electrical and fluidic connection between a sensing tip and an instrumented pipette.

Abstract: The invention concerns an observation device such as cell culture wells comprising an optical element such as a lens or a filter, or even combinations thereof, for compensating an optical effect induced on a sample contained in the observation device and illuminated by a light beam traversing a meniscus. The interaction of a light beam with a meniscus interposed between said light beam and a sample to be visualized, alters the image readout of the sample so that the image thereof results negatively affected. By aligning the optical axis of the optical element with that of the meniscus, an optical effect such as non-uniform light distribution of illumination of the sample can be conveniently compensated. The invention further discloses the optical elements, characterising the observation device, per se.
