The device (1) has substance carriers (2, 2') attached to a housing (3). The housing has lower and upper parts (3a, 3b) arranged at a distance from each other under formation of a gap (17) in which the carriers are partially arranged. The upper part has a contact surface abutting to a substance carrier contact surface, and the lower part has a contact surface abutting to another substance carrier contact surface. Distance (a) from the upper part to the lower part is variable by moving the upper part relative to the lower part along a connection axis (A). |
