A pipette (sometimes spelled as pipet) is a type of laboratory tool commonly used in chemistry and biology to transport a measured volume of liquid, often as a media dispenser. Pipettes come in several designs for various purposes with differing levels of accuracy and precision , from single piece glass pipettes to more complex adjustable or ...
The difference between the calibration mark of Serological pipette (top) and Mohr (bottom) A graduated pipette is a pipette with its volume, in increments, marked along the tube. It is used to accurately measure and transfer a volume of liquid from one container to another. [1] It is made from plastic or glass tubes and has a tapered tip. Along ...
A Mohr pipette, also known as a graduated pipette, is a type of pipette used to measure the volume of the liquid dispensed, although not as accurately as a volumetric pipette. [1] These use a series of marked lines (as on a graduated cylinder) to indicate the different volumes. [2] They come in a variety of sizes, and are used much like a ...
used for preparation of culture media and the culture of organisms they are in Glass beaker: reagent storage Glass flask: gastric acid, or other fluid titration: Pasteur pipette: for aspiration and addition of reagents Graduated pipettes: for aspiration and addition of reagents, often of minuscule amounts of the material; used mainly in ...
[2] [3] They thus are used for smaller-scale transfers than equipment such as graduated pipettes, which come in 5, 10, 25 and 50 mL volumes. The most common type of pipettes can be set to a certain volume within its operational range and are called adjustable. These pipettes commonly have a label with their volume range like "10–100 μL".
The Micropipette developed by Heinrich Schnitger, which is often referred to as "Eppendorf pipette" in laboratory usage, [citation needed] counts today in various designs as standard almost every biomedical laboratories. For biologists, biochemists, biology laboratory technicians, medical-technical assistants and similar professions handling of ...
