Microcentrifuge tubes are primarily designed to hold samples during centrifugation. They are specifically manufactured to withstand the forces generated during this process, ensuring that the samples remain secure and undisturbed as they are spun at high speeds. The shape and material of these tubes allow for efficient separation of components within the sample based on their densities, making them an essential tool in molecular biology, biochemistry, and various laboratory applications.

While microcentrifuge tubes can be used to mix chemicals, that is not their primary designed function. Their effectiveness in centrifugation is what distinguishes them in laboratory settings. Additionally, microcentrifuge tubes are not typically employed for measuring pH levels or for storing solid samples, tasks which are more suitable for other types of containers. Therefore, their primary use remains focused on providing a reliable environment for sample processing during centrifugation.
