A lid mechanism (1) is provided for laboratory equipment, and especially for polymerisation chain reaction thermal cycle apparatus. The lid mechanism (1) includes a lid (9) movable between an open position, in wich a sample may be inserted into or removed from the equipment, and a closed position, in which a sample is prevented from being removed from the equipment. The lid mechanism (1) also includes a drive mechanism (5, 6, 7, 8) coupled to the lid (9) and operable to move the lid (9) between the open and the closed position.
