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. The seating surfaces are frustoconical outer surfaces. The pipette nozzle may be further configured to sealingly mate with and removably receive a third pipette tip having a third diameter different from the first diameter and the second diameter.
