摘要：
A pipet device (A) includes a pipet nozzle (1) formed with an internal passage (10) and a hollow pipet tip (4) removably attached to the nozzle (1). The tip (4) is movable between a normal fixed position and a completely detached position relative to the nozzle (1). The nozzle (1) is formed with an external-air intake groove (16). The intake groove (16) is closed by the tip (4) when the tip (4) is at the normal fixed position. The intake groove (16) is exposed from the tip (4) when the tip (4) is moved from the normal fixed position toward the completely detached position.
