Answer 1

Answer:

Do not ever use your mouth to pull the liquid into a pipet. This is the most common method of becoming poisoned in a chemical laboratory or becoming infected in a clinical laboratory. Also, having the bulb attached to the pipet increases the risk of drawing the solution into the bulb.
