Abstract (en)

[origin: WO0053321A1] The invention concerns an apparatus (1) comprising at least a planar surface (2) whereat compartments (3) are found defined by a partition (4), the compartments producing a space enabling the independent displacement of at least one liquid sample (5 and/or 15) and, when there are at least two liquid samples (5 and 15), their independent displacement and their being contacted to produce a joint reaction. The compartments (3) consist at least of two different types of grooves: one first type of groove(s) said to be deep (6), serving as partitioning means of the sample(s) ( 5 and/or 15); and a second type of groove(s) said to be shallow (16), serving as receiving means of said sample(s) ( 5 and/or 15); the two types of grooves ( 6 and 16) enabling to guide the displacement of the sample(s) (5 and/or 15) depending of the orientation given to the apparatus (1). The invention is applicable to microfluidic devices used in biology.
