Autosampler system with dual rotational axis uncapping

An autosampler system comprising:

• a sample rack;
• a sample vessel stabilizer configured to transition the sample rack between a load/unload state and a lock state;
• an uncapper supported by a first z-axis support, the uncapper including an uncapper body and a cap interface rotationally coupled to the uncapper body, the uncapper body coupled to the first z-axis support;
• a sample probe supported by a second z-axis support;
• a motor system configured to provide at least rotational motion and translational motion to each of the first z-axis support and the second z-axis support, wherein the uncapper is configured to remove a cap from a sample vessel held by the sample rack via interaction between the cap interface and the cap when the sample rack is in the lock state, and wherein the uncapper is configured to change the position of the removed cap via rotational motion of the uncapper body to permit access to an interior of the sample vessel by the sample probe without removing the sample vessel from the sample rack;
• and
• a deck configured to support at least a portion of the sample rack on top of the deck, the deck defining at least one channel through which the first z-axis support and the second z-axis support are configured to pass during translational motion,
• wherein the cap interface is configured to rotate about a rotational axis separate from the first z-axis support.
