What is the function of a transfer pipet in experiments?

The function of a transfer pipet is primarily to dispense liquids or chemicals in a controlled manner during experiments. Transfer pipets allow for the precise transfer of small volumes of liquid samples, which is crucial in biochemical experiments and assays where accurate measurement and transfer of reagents can significantly affect outcomes.

The design of transfer pipets typically includes a bulb that creates suction, enabling the user to draw up liquid and then dispense it as needed. This functionality is essential in laboratories for tasks such as mixing solutions, conducting dilutions, or adding reagents to reaction vessels without the risk of contamination or spillage.

In contrast, the other options either describe functions that do not relate to the specific use of transfer pipets or assign them roles that are not characteristic of their design and purpose in a laboratory setting.
