If its in the pipe: By using rubber bulb, the contact of the mouth to the chemicals can be avoided.
Place the end of the pipet well below the surface of the liquid to be transferred and gently release the bulb.
How to use a pipette filler bulb. It serves as a vacuum source for filling reagents through a pipette or pasteur pipette and also help control the flow of liquid from the dropping bottle. Natural rubber bulb allows safe, manual control of filling or discharging toxic liquids through a pipette by finger pressure (thus avoiding mouth contact). Pipette doesn't come in contact with hard plastic, thus reducing the risk of cracking and chipping.
Liquid should be drawn up into the. It's very handy for those few reagents we need to reconstitute. Pipette filler bulbs have replaced unsafe mouth pipetting, by introducing a manual liquid aspiration transfer using simple squeezing and releasing action.
This pipette aid is used by squeezing, then releasing the bulb to aspirate fluid into the pipette. Most likely it is in the pipe. Mickie kim nielson from ut wrote (october 12, 2018):
