SYSTEM AND METHOD FOR AUTOMATICALLY VENTING AND SAMPLING A CULTURE SPECIMEN CONTAINER

摘要

Apparatus for automated venting and/or sampling of a specimen container having a closure sealing the interior of the specimen container from the environment is disclosed. The apparatus includes a rack holding the specimen container; a venting and/or sampling device having a needle, a chamber in fluid communication with the needle and a port in fluid communication with the chamber; a robotic transfer mechanism moveable relative to the rack; a sample removal apparatus attached to the robotic transfer mechanism having gripping features for gripping the venting device. The sample removal apparatus and robotic transfer mechanism are moveable relative to the specimen container so as to automatically insert the needle of the venting device through the closure of the specimen container to thereby vent the interior of the specimen container and obtain equilibrium between the interior of the specimen container and the atmosphere and withdraw a portion of the sample from the specimen container into the venting and/or sampling device.
