摘要： A pipette nozzle is provided for use on a movable arm on an automated pipette machine. The pipette nozzle includes a body defining a passage therethrough and having at least two seating surfaces provided on the body. The first seating surface is configured to receive and sealingly mate with a first size of pipette tip in a manner such that the first end of the passage is in fluid communication with the first size of pipette tip. The second seating surface is configured to correspondingly receive, sealingly mate and provide passage first end fluid communication with a second size of pipette tip. There is also provided an automated pipette machine which includes a tip ejector system including an arm that is movable between a first position and a second position wherein in the first position the arm is positioned to engage the tip during movement of the nozzle along a selected path and to prevent movement of the tip along the selected path while permitting the nozzle to move along the selected path, so that the movement of the nozzle along the selected path causes the nozzle and the tip to disengage from each other, and wherein in the second position the arm is positioned to avoid engagement with the tip during movement of the nozzle.

摘要： A pipette nozzle is provided for use on a movable arm on an automated pipette machine. The pipette nozzle includes a body defining a passage therethrough. At least two seating surfaces are provided on the body, including a first seating surface and a second seating surface. The first seating surface is configured to receive and sealingly mate with a first size of pipette tip in a manner such that the first end of the passage is in fluid communication with the first size of pipette tip. The second seating surface is configured to receive and sealingly mate with a second size of pipette tip in a manner such that the first end of the passage is in fluid communication with the second size of pipette tip. There is also provided an automated pipette machine which includes a tip ejector system including an arm that is movable between a first position and a second position, wherein in the first position the arm is positioned to engage the tip during movement of the nozzle along a selected path and to prevent movement of the tip along the selected path while permitting the nozzle to move along the selected path, so that the movement of the nozzle along the selected path causes the nozzle and the tip to disengage from each other, and wherein in the second position the arm is positioned to avoid engagement with the tip during movement of the nozzle. There is also provided an apparatus for use on an automated pipette machine for transmitting pressure changes produced by a pump on the machine to a pipette nozzle. The apparatus comprises a housing defining a chamber a first conduit and a second conduit. The first conduit extends into the chamber and has a first opening positioned in the chamber. The first conduit is fluidically connectible to the nozzle. The second conduit extends into the chamber and has a first opening positioned in the chamber. The second conduit is fluidically connectible to the pump. The first opening of the first conduit is positioned above the first opening of the second conduit. The chamber defines at least a selected volume between the height of the first opening of the first conduit and the height of the first opening of the second conduit.
