"用移液器吸取" can be translated as "aspirate with a pipette" or "draw up (a liquid) using a pipette".
“Aspirate with a pipette” is a more technical and precise expression, often used in laboratory or scientific contexts.
“Draw up (a liquid) using a pipette” is a more straightforward and common way to say it, suitable for general communication.
