Which tool is used to draw liquids up into a pipet tube and is squeezed to perform actions?

• A. Pipetting Bulb
• B. Pipette Pump blue
• C. Medicine Dropper
• D. Pipetting Device

Answer: (A)

The key idea is using a suction tool designed to work with a pipette. The pipetting bulb fits on top of a pipette and, when you squeeze it, it creates suction that pulls liquid up into the pipette. Releasing pressure lets you control the amount you dispense, giving you precise, predictable transfers. This is the standard method for aspirating and delivering liquids with a pipette in many labs. A medicine dropper isn’t intended to attach to a pipette for precise, volume-controlled transfer, and while a blue pipette pump or other devices can be used in different setups, the pipetting bulb is the most straightforward and appropriate tool for drawing liquid into a pipette and then dispensing it.
