(54) Title: DEVICE SUITABLE FOR VACUUM ASSISTED FILTRATION (57) : A funnel-less filtration device that attaches directly to a storage container such as a cell culture media bottle. The device includes a filter collar containing one or more mem- branes, an inlet with a coupling device for attaching the filter device to a supply of liquid to be filtered, an outlet at a lower portion of the collar, a vacuum port in the collar below the membrane(s) and a filtered vent in the collar above the membrane(s). Optionally, the device may include a filtrate reservoir attached to the outlet, preferably by a threaded connection. Optionally, the upper opening to the filter collar is selectively and removably sealed with a lid until used. The lid is then removed the filter device inverted over a storage container such as cell culture media bottle and the two are attached via the upper opening of the filter collar. The assembly is then inverted so the supply container is above the filter device. Upon subjecting the sample in the bottle to a driving force such as vacuum, the sample flows through the fil- tration element, and into a filtrate reservoir below the outlet of the filter collar.
