Abstract

A hand-held vacuum device includes a housing to hold an electrical motor operable to drive a piston pump that is configured to draw a substantially continuous vacuum for each complete cycle of the piston pump. The hand-held vacuum device also includes an expansion chamber releasably connected to and in fluid communication with the housing and a vacuum interface that has a vacuum connector in fluid communication with the expansion chamber and is configured to releasably couple to a valve disposed on a container. The expansion chamber separates air and liquid from a fluid drawn into the expansion chamber.
