What name is given to the graduated glass tube used to measure small precise amounts of liquids during titration in chemical analysis?
Titration side arm, and coined the terms "pipette" and "burette" in an 1824 paper on the standardization of indigo solutions. The first true burette was invented in 1845 by the French chemist Étienne Ossian Henry (1798–1873). A major breakthrough in the methodology and popularization of volumetric analysis was due to Karl Friedrich Mohr, who redesigned the burette into a simple and convenient form, and who wrote the first textbook on the topic, "Lehrbuch der chemisch-analytischen Titrirmethode" ("Textbook of analytical chemistry titration methods"), published in 1855. A typical titration begins with a beaker or Erlenmeyer flask containing a very precise volume of
Graduated pipette Graduated pipette 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. It is made from plastic or glass tubes and has a tapered tip. Along the body of the tube are graduation markings indicating volume from the tip to that point. 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
