Abstract SAMPLE TRANSFER SYSTEM WHEREIN THERE IS A FIXED OVERHEAD TRAVEL PATH WITH DEFINED SAMPLE TAKE-UP AND SAMPLE DISCHARGE STATIONS ALONG SAID TRAVEL PATH. A TROLLEY IS MOUNTED ON AND DISPOSED FOR MOVEMENT OF A LIFT MECHANISM ALONG SAID TRAVEL PATH. FIRST AND SECOND GROUP OF CONTAINERS ARE SIMULTANEOUSLY MOVED UP TO THE SAMPLE TAKE-UP AND SAMPLE DISCHARGE STATIONS BY MOVING A PLATFORM FORWARD. MOUNTED ON THE TROLLEY IS A SAMPLING TIP AND MEANS TO AUTOMATICALLY MOVE SAID TIP UP AND DOW, INTO AND OUT OF THE SAMPLE TAKE-UP AND SAMPLE DISCHARGE CONTAINERS, AS THESE ARE BROUGHT FOREARD TO THE RESPECTIVE STATIONS. CONNECTED TO THE SAMPLE TIP BY MEANS OF A FLEXI- BLE TUBE ARE A FIRST BARREL AND PISTON MEANS TO ACQUIRE AD EJECT A LIQUID SAMPLE FROM THE SAMPLE TAKE-UP CONTAINER, AND A SECOND AND THIRD BARREL AND PISTON MEANS CONNECTED IN SERIES WITH THE FIRST BARREL AND PISTON MEANS. IN ADDITION A VALVE IS SUPPLIED TO SELECTIVELY CONNECT THE FIRST, THE SECOND, AND THE THIRD BARREL AND PISTON MEANS. THE MOVEMENT OF THE PISTONS AND THE TROLLEY MOVEMENT ARE CONTROLLED BY PROGRAM MEANS. PREFERABLY, THE BARREL AND PISTON MEANS ARE CAM ACTUATED, THE CAM MOVEMENT SETTING THE STROKE OF THE PISTON IS ADJUSTABLE BY A PRECISION ADJUSTMENT MEANS.
