A suction bulb or pipette pump to suction the sample.

Explanation:

There are different types of pipettes that can be used in a laboratory:

  • Volumetric pipette-used to transfer a specific calculated amount of liquid
  • Graduated pipettes-used to transfer different calculated amounts of liquid from one container to another.
