Pipettes come in various sizes.
Micro pipettes can deliver microlitres.
20.0 mL pipettes can deliver 20.0 mL. Some pipettes are graduated, some are not.
It is not uncommon to have a range of pipettes in the laboratory - 5, 10, 20, 25 mL
A Mohr pipette is a type of pipette that measures the volume of dispensed liquids. It is less accurate compared to a volumetric pipette.
An automatic pipette is a piece of laboratory equipment that is used in transferring small liquid volumes. It is known to be both accurate and precise.
These are the most simple pipettes, used to extract and deliver pharmaceutical products.

A pipette filter is a tool used to fill pipettes, which are small and sometimes fragile, and thus difficult to fill without any tools. Pipette filters act as funnels that attach to the top of the pipette and have a mechanism to pour into it.
To safely draw liquids into a 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.
A Mohr pipette is a type of pipette that measures the volume of dispensed liquids. It is less accurate compared to a volumetric pipette.
An absorption pipette is a glass apparatus used in the absorption of gases.
The pipette is used to draw up fluids, some like using a straw.
The purpose of a volumetric pipette is to deliver a precise amount of a liquid. The label on the pipette indicates the volume delivered (e.g. 10.00 mL).
The mouth should never be used to suck liquid into a pipette. This is because it can be dangerous due to potential exposure to harmful chemicals, contamination of the sample, and inaccurate measurements. It is recommended to use a bulb or pipette aid to safely draw liquid into the pipette.
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.
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.
A pipette filter is a tool used to fill pipettes, which are small and sometimes fragile, and thus difficult to fill without any tools. Pipette filters act as funnels that attach to the top of the pipette and have a mechanism to pour into it.
to collect liquids
A pipette bulb or pipette filler should be used to safely draw and dispense liquids with a pipette. This device helps prevent exposure to hazardous chemicals and helps control the flow of liquids with accuracy.
