Also disclosed herein are systems including the disclosed devices. The systems include liquid in one or more of the chambers of the device. Methods of using the devices and systems include producing a vacuum by flowing a liquid through the bottom chamber of the system. Due to the difference in size of the inlet and outlet in the bottom chamber, a vacuum is produced in the top chamber.
