Abstract: A hydrodynamic focusing device, preferably realized as a microfluidic device, comprises a first flow channel (4); a smaller second flow channel (8); an envelopment region (12) connected in-line between the first (4) and the second (8) flow channels; and a chimney (14) comprising a body (16) and a sample fluid inlet (18), which extends from a, preferably sloped, wall (20) delimiting the envelopment region (12) and into the envelopment region (12). The body (16) and the sample fluid inlet (18) are each formed with an elongate, preferably teardrop-shaped, profile having a leading edge (28) facing the first flow channel (4) and opposing long edges (30a, 30b) relatively tapered towards a trailing edge (32).
