A device (1) suitable for marking a laboratory sample cassette (2) has a platen (6) with an aperture (7) and a cassette (2) is positioned so that a marking surface (3) of the cassette is aligned with the aperture (7). The device (1) also has a plurality of wires (9) with each wire (9) connected to a solenoid (11). An end (10) of each of the wires (9) is heated by a ceramic guide (12a) and selected ones of the heated wires (9) are oscillated once in a first direction (25) by their respective solenoids (11) to and from the aperture (7) to mark the marking surface (3). All the wires are then moved in a second direction transversely relative to the first direction (25) and selected wires are then oscillated once to mark the marking surface (3). This process is repeated until the required marking of the cassette marking surface (3) is completed.
