A burette (also spelled as buret) [1] is a graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations. It is a long, graduated glass tube, with a stopcock at its lower end and a tapered capillary tube at the stopcock's outlet. The flow of liquid from the tube to the burette tip is controlled ...
Different types of graduated cylinder: 10mL, 25mL, 50mL and 100mL graduated cylinder. A graduated cylinder, also known as a measuring cylinder or mixing cylinder, is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount ...
Graduated pipettes are considered to be more precise than the Pasteur pipette. They have tolerances that range from ±0.6% to ±0.4% of the nominal volume when measured at 20 °C (68 °F). Graduated pipettes are manufactured according to ISO specifications for accuracy and the arrangement of the graduations. Grade A and AS pipettes have the ...
French chemist François-Antoine-Henri Descroizilles developed the first burette (which was similar to a graduated cylinder) in 1791. [8] [9] [10] Gay-Lussac developed an improved version of the burette that included a side arm, and invented the terms "pipette" and "burette" in an 1824 paper on the standardization of indigo solutions.

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 ]
Graduated pipettes are a type of macropipette consisting of a long tube with a series of graduations, as on a graduated cylinder or burette, to indicate different calibrated volumes. They also require a source of vacuum; in the early days of chemistry and biology, the mouth was used.
