There are many types of pipettes (or pipet), but most are essentially a fancier version of a medicine dropper or eye dropper. They are used in a laboratory to transport and/or measure a specific volume of liquid.
Volumetric pipettes allow the user to measure a volume of solution extremely accurately and then add it so something else. They are commonly used to make laboratory solutions from a base stock as well as prepare solutions for titration. They typically only allow you measure one single volume in a particular size pipette (just like with volumetric flasks). Therefore, they come in many different sizes.
There are other types of pipettes also, such as a Pasteur pipette, which is not used to measure the volume of the liquid. It is essentially a large dropper, which can be used to remove liquid from one container and add it to another.
There are also graduated pipettes, also called a Mohr pipette, which also allow you to measure the volume of the liquid in the pipette, although not as accurately as a volumetric pipette. These use a series of marked lines (as on a graduate cylinder) to indicate the different volumes. These also come in a variety of sizes. These are used much like a burette, in that the volume is found by calculating the difference of the liquid level before and after.
All glass pipettes require the use of some kind of additional suction device, typically a pipette bulb (not the Eppendorf pipette or other similar ones, which have a built-in suction mechanism), which is a rubber bulb which sucks the liquid into the pipette and also allows you to drain the pipette in a controlled fashion. A Beral pipette is a one-piece pipette, usually made from flexible soft plastic (polyethylene) that has a built-in bulb on the end.

*A piece of laboratory glassware, shaped like a thin tube with a bulge in the middle, that allows better accuracy when measuring certain volumes (hence the range of sizes) e.g. when making solutions or samples for titrations.
Function of a pipette: to deliver small and exact volumes of liquids; extremely useful in chemical laboratories.
A pipet and a pipette are both tools used in laboratories for measuring and transferring liquids. The main difference between them is their design and usage. A pipet typically refers to a glass or plastic tube with a tapered tip used for transferring precise volumes of liquid. On the other hand, a pipette usually refers to a more sophisticated tool with a bulb or mechanism for drawing and dispensing liquid accurately. Both are essential for conducting experiments and ensuring accurate measurements in laboratory settings.
The correct term for the laboratory tool used for transferring small amounts of liquid is "pipette."
A pipette is a more precise and accurate tool used for measuring and transferring small volumes of liquid in laboratory settings. It typically has a built-in mechanism for controlling the volume being dispensed. On the other hand, a pipet is a more general term that refers to any type of liquid transfer device, including pipettes. The key difference lies in the level of precision and control offered by a pipette compared to a pipet, which can impact the accuracy and reliability of experimental results in a laboratory setting.
A dropper or pipette is typically used to transfer a small amount of the sample containing the protists onto a microscope slide. This ensures precise and controlled placement of the protists for viewing under the microscope.
A Pasteur pipette is commonly used in laboratories to transfer small amounts of liquid. It is useful for adding precise volumes of liquids, such as reagents or samples, to test tubes or other containers. The pipette allows for controlled and accurate dispensing of liquid.
You could use a pipet or a dropper depending on how much liquid you wish to transfer.
In one type of experiment, a pipet is used to distribute DNA information. The process is used in Gel Electrophoresis. With the pipet you syphon the DNA material and the chemicals used to bring out the genetic information and you squirt it into the notches in the gel. That is how a pipet is used in one instance.
A funnel is commonly used when transferring liquids from one container to another to minimize spills and ensure accurate pouring. It helps guide the liquid into the desired container while preventing splashing or waste. Funnel sizes and materials can vary based on specific needs and types of liquids being transferred.
A eye dropper is used to measure right amount of chemicals
A medicine dropper is used to transfer small amounts of liquid.
It is used to measure small and large quabtities
In science, a dropper is used for transferring small amounts of liquid from one vessel to another. A dropper is also known as a Pasteur pipette.
