Posted (2 days ago) One major difference between a burette and pipette is that a pipette is hand-held and a burette is typically clamped onto a stand on the laboratory bench. Both are long thin hollow tubes that are designed to hold liquids.
There are many advantages and disadvantages to each of the volumetric glassware devices used in this lab. The advantage of the Burette is that it is accurate with delivering solution and a disadvantage is that it is calibrated from top to bottom because it is designed to dispense liquids making it harder for the meniscus to be read. The volumetric pipette is precise with delivering solutions.
2021-5-12 · The burette requires two readings the initial reading and the final reading. The volume delivered is obtained by subtraction of the initial reading from the final reading. There is an uncertainty of ± 0.05 in each reading ∴ total absolute uncertainty of ± 0.1 ml. The percentage uncertainty = (0.1/24.2) x 100 = 0.41 uncertainty.
