Thermal cycler cover

A thermal cycler system, comprising:

• a device housing including:
• a sample block with a top and a bottom surface;
• a thermal electric device in thermal communication with the bottom surface;
• and
• a cover operably connected to the device housing, the cover being moveable between an open position to provide access to the sample block and a closed position to cover the sample block, the cover comprising:
• a handle portion having a distal side and a proximal side, the handle portion comprising an elliptical slot opening disposed at a proximal side of the handle portion and extending in a distal-to-proximal direction from a first terminal end to a second terminal end of the elliptical slot opening, the distal side of the handle portion being positioned to be grasped by a user to elevate the handle portion relative and to lower the handle portion;
• a device lid portion coupled to the proximal side of the handle portion via a first pin received and moveable in the elliptical slot opening;
• a sample block platen operably connected to the handle portion such that the sample block platen is positioned against the sample block when the handle portion is in a flush position with the device lid portion and the cover is in the closed position;
• and
• a link bar pivotably connected to the device housing at a first end portion of the link bar, the link bar having a second end portion, opposite the first end portion, connected to a second pin extending into and moveable along the elliptical slot opening of the handle portion, wherein:
• the handle portion is configured to be elevated away from and relative to the device lid portion before the cover is moveable to the open position,
• the second pin is configured to move along the elliptical slot opening in a direction toward the first terminal end of the elliptical slot opening as the handle portion is elevated relative to the device lid portion, and
• in the position of the second pin at the first terminal end of the elliptical slot opening and in response to continued elevation movement of the handle portion, the handle portion and the device lid portion are moveable together to move the cover to the open position.
