A laboratory liquid handling system comprising: a pipetting module including first and second pipettors (72, 74), the first and second pipettors including first and second pipettor shafts, respectively, a first pipetting tip extending from an end of the first pipettor shaft, and a second pipetting tip extending from an end of the second pipettor shaft; characterized by: a lab member including a lab object and first and second integral adapter structures (122, 128) configured to engage the first and second pipettor shafts, respectively, wherein the first adapter structure is configured to releasably secure the lab member to the first pipettor shaft; and a drive system operable to: selectively engage the first pipettor shaft with the first adapter structure to secure the lab member to the pipetting module; selectively engage the second pipettor shaft with the second adapter structure; move the pipetting module to transport the lab member secured thereto; and selectively disengage the first pipettor shaft from the first adapter structure to thereby release the lab member from the pipetting module. a pipetting module including first and second pipettors (72, 74), the first and second pipettors including first and second pipettor shafts, respectively, a first pipetting tip extending from an end of the first pipettor shaft, and a second pipetting tip extending from an end of the second pipettor shaft; characterized by: a lab member including a lab object and first and second integral adapter structures (122, 128) configured to engage the first and second pipettor shafts, respectively, wherein the first adapter structure is configured to releasably secure the lab member to the first pipettor shaft; and a drive system operable to: selectively engage the first pipettor shaft with the first adapter structure to secure the lab member to the pipetting module; selectively engage the second pipettor shaft with the second adapter structure; move the pipetting module to transport the lab member secured thereto; and selectively disengage the first pipettor shaft from the first adapter structure to thereby release the lab member from the pipetting module. a lab member including a lab object and first and second integral adapter structures (122, 128) configured to engage the first and second pipettor shafts, respectively, wherein the first adapter structure is configured to releasably secure the lab member to the first pipettor shaft; and a drive system operable to: selectively engage the first pipettor shaft with the first adapter structure to secure the lab member to the pipetting module; selectively engage the second pipettor shaft with the second adapter structure; move the pipetting module to transport the lab member secured thereto; and selectively disengage the first pipettor shaft from the first adapter structure to thereby release the lab member from the pipetting module. selectively engage the first pipettor shaft with the first adapter structure to secure the lab member to the pipetting module; selectively engage the second pipettor shaft with the second adapter structure; move the pipetting module to transport the lab member secured thereto; and selectively disengage the first pipettor shaft from the first adapter structure to thereby release the lab member from the pipetting module.
