Abstract:
An apparatus for transporting sample well trays with respect to a heating device, comprising:a sample well tray holder comprising a plate for positioning a sample well tray therein, the sample well tray holder configured to rotate about a first rotational axis between a first position outside the heating device and a second position inside the heating device; a rotational actuator comprising a motor and a shaft attached to the motor, the rotational actuator being configured to rotate the sample well tray holder about the first rotational axis; and a biasing mechanism configured to urge the sample well tray holder in a generally upward direction along the first rotational axis, wherein the shaft attached to the motor is a spline shaft, the rotational actuator further comprising a spline bushing for engaging with the spline shaft so that the spline bushing is rotationally fixed but axially moveable relative to the spline shaft.
