Historically, the accuracy of a graduated pipette was not as good as that of a volumetric pipette (accuracy of 3 significant figures); however, with improved manufacturing methods, the accuracy listed by the manufacturer can equal that of a volumetric pipettes. Graduated pipettes are considered to be more precise than the Pasteur pipette. They ...
Graduated cylinders are often used to measure the volume of a liquid. Graduated cylinders are generally more accurate and precise than laboratory flasks and beakers, but they should not be used to perform volumetric analysis; [3] volumetric glassware, such as a volumetric flask or volumetric pipette, should be used, as it is even more accurate ...
A volumetric pipette, bulb pipette, or belly pipette [1] allows extremely accurate measurement (to four significant figures) of the volume of a solution. [2] It is calibrated to deliver accurately a fixed volume of liquid. These pipettes have a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a ...
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 ]
For example, a motorized pipette controller can aid liquid aspiration or dispensing using volumetric pipettes or graduated pipettes; [13] a tablet can interact in real-time with the pipette and guide a user through a protocol; [14] and a pipette station can help to control the pipette tip immersion depth and improve ergonomics.

The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined. [5] Compared to a volumetric pipette, a burette has similar precision if used to its full capacity, but as it is usually used to deliver less than its full capacity, a burette is slightly less precise than a pipette.
