Abstract

A pipette has a tip having at the front end thereof an inlet/outlet hole through which a liquid is sucked up and delivered. The pipette is fitted at an opening formed therein with an air passage through which air is sucked out from inside the pipette tip or supplied into the pipette tip. The pipette includes an inflatable member secured to the pipette body and which can be inflated with a fluid charged therein. The pipette body has formed therein separately from the air passage a fluid passage through which a fluid is charged and discharged. The inflatable member when charged with the fluid through the fluid passage in the pipette body and thus inflated closely adheres to the inner wall or outer surface of the top end portion of the pipette tip where the opening is formed, to thereby securely catch the pipette tip.
