Not at all sure. But they can be used to separate anything with a disparity in weight. Milk and cream, oil and water, organic matter from liquid where a strainer is inefficient.

Of course the usual Bureaucratic mindset of, "let's not let anyone know, till we want to," seems to be in place, and even then we will only receive part of the story, if and when.
