Web because of its smaller meniscus, a buret is more accurate and precise than a graduated cylinder. That means when you read the volume, you can estimate to the hundredths place (0.01 ml). However, like any other measuring instrument, they only have a limited accuracy and precision. Some graduated pipets can be filled to the desired level and then drained completely. The volume delivered is the difference between the two readings as is the case with a buret or a graduated cylinder.
Web the volume of a liquid can be directly measured with specialized glassware, typically in units of milliliters (ml) or liters (l). Burets are best for titration. Web its use requires an initial meniscus reading and a final meniscus reading; You can estimate one more digit past the smallest division on the measuring device. Study with quizlet and memorize flashcards containing terms like beaker adv, beaker disadvantageous, buret adv and more.

Web when observing a volume of a liquid in a graduated cylinder, graduated pipette, or buret, read the point on the graduated scale that coincides with the bottom of the curved surface of the liquid.
Volumetric flasks, burets and pipets are the most accurate with tolerances of less than 0.2%. You must use the bottom of the meniscus to determine the volume in the 10 ml graduated cylinder. Web key differences a burette is a long, cylindrical glass tube with graduation marks and a valve or stopcock at the bottom, allowing controlled liquid release. For greater accuracy, use a pipet or a buret.
Web In Summary, A Burette Is Preferred Over A Measuring Cylinder For Precise Volume Measurements, Especially In Titrations.
For greater accuracy, use a pipet or a buret. In this lab, a beaker, two graduated cylinders and a burette will be used to measure liquid volumes, and their precision will be compared. Web its use requires an initial meniscus reading and a final meniscus reading; The burette is more effective at delivering a precise volume than it is for titrations.
A Measurement Made With A Buret Should Be To The Hundredths Place (Ex:
A pipet has no scale and is designed to deliver only one volumetric quantity of liquid and you must read the calibration value on the pipet to determine the number of significant digits. Burets are best for titration. As with the graduated cylinder, the buret volumes are read at the bottom of the meniscus (see figure 2.).
