Filtering Flask


This type of flask with a horizontal tube attached to the neck was known as a filter flask, a filtering flask, or a suction flask. The form was in use by the 1890s, for filtering under reduced pressure. It was sometimes associated with Robert Bunsen, professor of chemistry at the University of Heidelberg.
