I thought these devices were called pipettors not strictly micropipettes?
Pipettes are originally the glass tubes of fixed or graduated volume, but the definition has expanded to include air displacement pipettes aka "micropipettes" (even when the volume is measured in milliliters not microliters, they are still colloquially micropipettes).
The pipet is considered the tube, the pipettor is the mechanical attachment, I would say that is whether the attachment is with lips & tongue or not.
