                     Proprietary Structure for Ensuring Sample Cooling


                     SIL-40 series autosamplers include a direct-access function that helps improve analytical operating efficiency by allowing
                     additional sample vials or MTP plates to be inserted even during data acquisition. A dry air flow control system ensures
                     reliable sample cooling and relieves operators from the inconvenience of dealing with condensation water.
