Abstract: The present invention relates to the latching closed of doors on appliances. In particular, the present invention provides an advantageous apparatus for locking the lid of a centrifuge. Apparatus for locking an appliance door in a closed position, the apparatus comprises: a locking member for attachment to a door, the locking member having an engagement section; a locking bolt for engaging the engagement section in the locking member; a linear actuator for moving the locking bolt along an axis, wherein the linear actuator is self-locking.

Abstract: The present invention relates to a centrifuge, in particular a laboratory centrifuge, comprising a rotor which is rotatably mounted in an interior of a rotor chamber and is designed to accommodate sample vessels, a drive motor to set the rotor in rotation, and a cooling device which is designed to dissipate heat from the interior of the rotor chamber via a coolant, the cooling device being designed to use an elastocaloric effect and having at least one cooling unit which comprises an elastocaloric material arranged between a counter block and a punch, the punch being designed to periodically apply a force to the elastocaloric material and then to let the elastocaloric material relax again, the cooling device being designed to transfer both heat from the elastocaloric material to the coolant and from the coolant to the elastocaloric material. The present invention also relates to a method for cooling an interior of a rotor chamber of such a centrifuge.
