The Pasteur pipette is designed specifically for transferring small volumes of liquid. It is a simple, uncalibrated tube with a tapered end and is often used for dispensing liquids in varying amounts, typically for applications in biology and chemistry where high precision is not required. This makes it ideal for tasks such as transferring reagents or samples where exact measurements are less critical.

In contrast, graduated pipettes and volumetric pipettes are designed for high precision and accuracy in measurements. Graduated pipettes allow for measurement at various levels, while volumetric pipettes are used to measure a specific volume of liquid very accurately. Micropipettes, on the other hand, are used for transferring very small volumes of liquid with high precision and often include features for accurately setting specific volumes. Therefore, the Pasteur pipette stands out as the correct answer for transferring small volumes without a need for high precision.
