초록 ▼

A vacuum filter device is disclosed which includes a filter body which is adapted to receive in fluid-tight, sealed relationship a pair of closed containers for solutions to be filtered by a membrane filter positioned within the filter body. A vacuum port in the filter body communicates with the downstream side of the membrane and a venting passageway also located in the filter body communicates with the closed sample container to serve as a vent to atmospheric pressure. The venting passageway is made of an air permeable hydrophobic filter or preferably a small enough opening to prevent the sample solutions from leaking out of the device during normal use.

대표청구항 ▼

[ We claim:] [1.] A vacuum filter device comprising:a single filter body having two holders disposed from one another, each of said holders to receive respective feed and filtrate containers;each of said holders including sealing means for creating a liquid tight seal when said containers are coupled to said filter body, said feed container for housing a liquid to be filtered and said filtrate container for receiving the filtered liquid, each of said containers forming liquid tight receptacles when coupled to said filter body;a filter sealed within said filter body between said holders so that liquid in said feed container must pass through said filter prior to entering said filtrate container;a vacuum port extending through said filter body and being in fluid communication with said filtrate container at a downstream side of said filter, said vacuum port adapted to be connected to a vacuum source for drawing said liquid from said feed container through said filter and into said filtrate container; anda vent passageway in said filter body configured to permit gas in the atmosphere surrounding said vacuum filter device to be in direct fluid communication with said feed container on an upstream side of said filter and not to be in direct fluid communication with said filtrate container.
