Lab Funnel Functionality

A funnel is a cone shaped apparatus designed to introduce liquid into a container with a small opening and to reduce spillage. Given the frequency of liquid transfer in biological labs, it is smart to keep funnels on hand for ease of use. For lab use, funnels are typically made of low-density polyethylene, polyethylene, polystyrene or polypropylene to improve chemical resistance. Other funnels can be sterilized or autoclaved for reuse, and can sometimes be graduated.

Filling & Separatory Funnels

The most common type of funnel is known as a filling funnel, and as the name suggests, is used to fill containers.

Another kind of funnel is a separatory funnel, which is used to separate different chemicals within a solution into two phases thanks to differing densities. Due to their functionality, separatory funnels are usually made of a chemically resistant material such as borosilicate glass.

One other funnel used in the lab is known as an addition funnel, which is a cylindrical tube with a stopcock to slowly dispense a single drop of liquid.
