In preparing samples for centrifugation, what equipment assists in transferring liquids?

Using a funnel for transferring liquids during the preparation of samples for centrifugation is appropriate because funnels are specifically designed to guide liquids into containers with narrow openings, minimizing spills and ensuring accuracy. This is particularly important in laboratory settings where maintaining the integrity of the sample is crucial.

While a scalpel is used for cutting or dissection, it does not assist in transferring liquids. A graduated cylinder is primarily used for measuring liquid volumes rather than transferring them, providing an accurate measurement but not helping with the movement of liquids. A balance scale is used to measure mass and is unrelated to the handling of liquid samples. Therefore, the funnel is the best choice for facilitating precise and efficient liquid transfer in preparation for centrifugation.
