Question: why are volumetric pipettes more accurate?
Answer: Volumetric pipets are so accurate because the long neck decreases the error in measuring volume of the meniscus. They are only designed to measure one specific volume and commonly come in sizes 5 mL, 10 mL, 25 mL, and 50 mL. ... The pipet is read by placing the bottom of the meniscus on the measuring line.
