A gripper for picking and placing an object, in particular a microtiter plate (10), has two mutually spaced gripper jaws (1, 2) and an actuation device (3, 4, 5) for changing the distance between the two gripper jaws (1, 2) so as to clamp the object (10) between the gripper jaws (1, 2). Each gripper jaw (1, 2) has a gripper finger (6, 7) made of a first material and having a fingertip (8, 9) coated with a second material which is in contact with a contact zone (11, 12) of the object (10) when the object is clamped, the coefficient of friction between the second material and the material of which the contact zone (11, 12) of the object (10) is made being higher than the coefficient of friction between the first material and the material of which the contact zone (11, 12) of the object (10) is made. |
