Abstract
A manual liquid filtration device includes a housing having an open upper end providing access to an internal vacuum chamber, and defining a liquid specimen receiving chamber with a filter element adapted for fluid communication with the vaccum chamber. A sealed frangible ampule is contained within the housing. The ampule is evacuated and when broken will produce a vacuum within the housing. The vacuum draws liquid samples through the filter element.
