Why is pipette more accurate than burette?

Pipettes are generally more accurate than burettes because they are designed to deliver a fixed volume of liquid with high precision, often using a single, calibrated measurement. Burettes, on the other hand, allow for variable volume dispensing, which can introduce more potential for user error and inconsistencies in measurement. Additionally, pipettes often have a narrower tip that minimizes liquid retention and improves the precision of the dispensed volume.
