Abstract: The present invention relates to a process for mixing a heterogeneous solution containing at least two different liquids and, optionally, at least one solid entity, so as to obtain a homogeneous solution, the process comprising the following steps: a) all or part of the heterogeneous solution is placed in at least one vessel having a longitudinal axis; b) the vessel is positioned on a support driven about a rotation axis, the longitudinal axis being inclined to the rotation axis; and c) the support is made to undergo a movement so as to subject the solution contained in the vessel to successive accelerations and decelerations of sinusoidal intensity, thereby stirring said heterogeneous solution, which becomes homogeneous. The invention also relates to a device for implementing the above process. A preferential application of the invention is in the field of medical diagnostics.

Abstract: A device for preparing and/or treating a biological sample including an assembly of storage chambers and/or reaction chambers intended for receiving a fluid, the chambers being separated by walls so as to form an assembly of adjacent chambers. The device includes a base and a drawer including the assembly of adjacent chambers, the drawer being movable in relation to the base, the drawer including a contact surface connected to first means for establishing fluid communication connected to the inside of at least one chamber, the contact surface of the drawer being intended to be positioned facing a contact surface of the base including at least one position at which second means for fluid communication connected to detection means are placed.

Abstract: Methods for detecting the presence and/or volume and/or identity of liquid in a transparent carrier include directing a light source towards the carrier; recording an image of light refracted by the carrier with a camera; and deriving information regarding the presence and/or volume of the liquid in the carrier from the recorded image of the light refracted by the carrier. Devices for detecting the presence and/or volume and/or identity of liquid in a transparent carrier include a camera directed towards the carrier; a light source directed towards the carrier; and means for recording an image of light from the light source as refracted by the carrier and captured by the camera.
