2010-6-21 · The volumetric pipette is a device that is capable of deliv ering only one volume of liquid. This is unlike a graduated cylinder or buret that can deliver a broad range of volumes as they have graduated scales. The real advantage of the volumetric pipette is that it delivers its one volume very accurately precisely and reproducibly.
2018-12-19 · The scale divisions on a graduated cylinder are generally determined by its size. The 10-mL graduated cylinder scale is read to the nearest 0.01 mL and the 500-mL graduated cylinder scale is read to the nearest milliliter (1 mL). A buret is a scaled cylindrical tube attached to a stopcock or valve.

As you can see in the above tables the 5 mL pipette has the lowest tolerance and therefore the best accuracy followed by the 50 mL burette and the 10 mL graduated cylinder is the least accurate of the three. (The accuracy of the graduated cylinder is
2020-3-1 · Burettes are larger than a pipette it has a stopcock at the bottom to control the release of liquid.Burette is similar like graduated cylinder and is easier to measure a required volume of liquid through graduations. But it has large meniscus and hence its accuracy and precision is
The graduated pipette is typically used for the measurement of volumes up to 50ml. A graduated cylinder is commonly used for the measurement of larger quantities. You may also use a micropipette for measuring small volumes. A small pipette is often preferred over a large pipette to maintain greater precisionquantity permitting.
