A pipette is either a glass or plastic narrow tube with a rubber bulb on one end. The idea is to put the open end into a liquid, after depressing the bulb. On releasing the bulb, a suction is formed and liquid is drawn up the tube. The pipette can then carry the liquid to another receptacle. On squeezing the bulb, the liquid is deposited into the new receptacle.

What the function of the pipette?
The pipette is used to draw up fluids, some like using a straw.
Why should you not blow out the small amount of solution that remains in pipette when measuring liquids?
The calibration of a pipette is made taking into account this small volume.
Why should you not blow out the small amount of solution that remains in a pipette when measuring liquid?
The calibration of a pipette is made taking into account this small volume.
Why it not suitable to empty the last liquid drop of a pipette by blowing or any other method?
Because the calibration of the pipette was made ignoring this drop.
What is a pipette safety bulb?
A pipette bulb is the rounded part of a pipette which you squeeze the air out of, then release to draw liquid into the pipette. If you are using a calibrated glass pipette, it will be a separate piece made of rubber which is fitted to the pipette. If it is a simple plastic pipette then the bulb will be made of the same semi-transparent plastic, and the pipette will all be one piece.
What does a pipette looks like and how is it used?
A pipette typically looks like a long glass or plastic tube with a tapered tip and a squeezable bulb or plunger at one end. It is used to accurately transfer small volumes of liquid from one container to another. By squeezing the bulb or plunger and then releasing it, a specific volume of liquid can be drawn up into the pipette or dispensed out of it.
What is the purpose of a dropper pipette?
The purpose of a dropper pipette is to administer only a small drop of a liquid to something. The dropper pipette is a tool that will allow you to squeeze a single drop of the liquid it contains.
How Do pipettes suck up water?
Pipettes use suction to draw up liquid by creating a vacuum within the pipette tip. When you press the plunger to decrease the pressure inside the pipette, the liquid is pulled up into the tip due to the difference in pressure between the inside and outside of the pipette.
What is a pipette bulb use for in chemistry?
A pipette bulb allow a liquid to be sucked up into the pipette, so avoiding having to use your mouth to suck the liquid up. Apart from avoiding often toxic liquids getting into your mouth, it also avoids contamination of the liquid.
What do you call the instrument that holds the pipette?
The instrument that holds the pipette is called a pipette bulb or a pipette filler. It is used to create suction for drawing liquid into the pipette and controlling its release.
What is another name for Pasteur pipette?
Another name for Pasteur pipette is transfer pipette.
What is a Mohr Pipette used for in chemistry?
A Mohr pipette is a type of pipette that measures the volume of dispensed liquids. It is less accurate compared to a volumetric pipette.
