1. A device for delivering a laboratory sample carrier from a stack of sample carriers, the device comprising:

  • a retainer configured to retain a stack of laboratory sample carriers; and

    an ejector mechanism comprising;

    a carrier support portion and a carrier transporting portion which are hingeably interconnected, the carrier transporting portion having a carrier accommodating region and a stop;

    a motor to displace the carrier support portion from a first carrier receiving position and configuration to a second carrier release position and configuration, the carrier transporting portion arranged to support the stack when the carrier support portion is in the first carrier receiving position and configuration, the carrier support portion arranged to move a lowermost carrier from the bottom of the stack in the carrier accommodating region as the carrier support portion is displaced from the first carrier receiving position and configuration, and the carrier support portion is arranged to support the stack when the carrier support portion is in the second carrier release position and configuration;

    a release surface that releases said carrier from the carrier accommodating region when the carrier support portion reaches the second carrier release position and configuration, wherein the release surface is positioned to engage the carrier in the carrier transporting portion and displace the carrier past the stop of the carrier transporting portion when the carrier support portion reaches the second carrier release position and configuration; and

    a carrier transporting portion support for supporting the carrier transporting portion when the carrier support portion is in the first carrier receiving position and configuration but does not support the carrier transporting portion when the carrier support portion is in the second carrier release position and configuration thereby allowing the carrier transporting portion to drop to a carrier release position to release any said carrier from the carrier accommodating region, wherein the stop of the carrier transporting portion prevents a said carrier held in the carrier accommodating region from dropping from the carrier transporting portion before the carrier support portion reaches the second carrier release position and configuration.
