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, ...
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 ]
In the same year, he presented under the title "A rapid and precise pipetting of small liquid quantities" a patent at the German Patent Office one, issued in 1961. The company Eppendorf improved the first "Marburg pipette" apparatus in cooperation with Heinrich Schnitger, and took over the exclusive license of the patent for commercialization.
A small pipette allows for more precise measurement of fluids; a larger pipette can be used to measure volumes when the accuracy of the measurement is less critical. Accordingly, pipettes vary in volume, with most measuring between 0 and 25.0 millilitres (0.00 and 0.88 imp fl oz; 0.00 and 0.85 US fl oz). [2]
(These are for Class A pipettes; Class B pipettes are given a tolerance of twice that for the corresponding Class A.) A specialized example of a volumetric pipette is the microfluid pipette (capable of dispensing as little as 10 μL) designed with a circulating liquid tip that generates a self-confining volume in front of its outlet channels.

March 14th marks the annual Pi Day, a day dedicated to honoring the mathematical constant pi or π (aka 3.14). The day is also just a great excuse to bake up your favorite pie recipe !
An eye dropper, also called Pasteur pipette or simply dropper, is a device used to transfer small quantities of liquids. [1]
