What does a funnel used with conical centrifuge tubes do?

A funnel used with conical centrifuge tubes is designed to facilitate the transfer of liquids into the tubes without spillage, which is especially crucial when dealing with small openings and potentially hazardous or valuable samples. The funnel’s shape allows it to guide the liquid efficiently, ensuring that it fills the conical centrifuge tube accurately.

Utilizing a funnel in this context minimizes the chance of contamination or sample loss, which can be critical in scientific or medical settings. This function is specifically beneficial when preparing samples for centrifugation, as it streamlines the process and supports accurate laboratory practices.
