Abstract
A vacuum filter device comprising a filter body having two holders on opposite sides of a filter. Each holder contains a closed container in a fluid-tight, sealed relationship. The filter is retained by a compression sealing element and the sealing element is maintained in place by a compression element formed of a ring. The compression element is bonded to a portion of the body to hold it, the sealing element and filter in place under a compression seal. Optionally a port in the compression element is formed to align with the vent of the device. Further, an alignment feature on the compression element ensures the port is in alignment with the vent of the device. The device also includes a vacuum port communicating with the downstream side of the filter, and hence the filtrate container.
