Disclosed is a vacuum filtration device including; (a)filter body including a filter membrane; (b) a passageway extending through the body and communicating with the upstream side of the filter for receiving a fluid to be filtered; (c) a junction mounted on the body on the downstream side of the filter and adapted to receive a closed container for receiving the filtered fluid and including sealing for creating a fluid tight seal between the container and the body; (d) a vacuum port communicating with said junction and adapted to be connected to a vacuum source for drawing the fluid through the filter and comprising a sealable vacuum vent which, when open, provides fluid communication between the vacuum port and a gas source. The device also includes a vacuum vent cap and a filter body vent and vent cap.

[ We claim:] [1.] A vacuum filtration device, comprising:(a) filter body having a filter secured within said body;(b) passageway extending through said body and communicating with the upstream side of said filter for receiving a fluid to be filtered;(c) a junction mounted on said body on the downstream side of said filter, said junction being adapted to receive a closed container and including sealing means for creating a fluid tight seal between said container and said body, said container for receiving the filtered fluid; and(d) a vacuum port communicating with said junction, said port being adapted to receive a vacuum source for drawing said fluid through said filter into said container and comprising a sealable and openable vacuum vent which is constructed and arranged to provide, when open,fluid communication among said container, said vacuum source and a gas source. [2.] The vacuum filtration device of claim 1 further comprising a filter body vent providing fluid communication between the upstream side of the filter and said vacuum source. [3.] The vacuum filtration device of claim 2 wherein a hydrophobic filter is mounted to said filter body vent.
