The improvement is characterized by a first housing section with first peripheral edge and a second housing section with a second peripheral edge. One of the first peripheral edge of the first housing section or the second peripheral edge of the second housing section has a filter retaining groove. One of a rigid planar filter or a perforate rigid planar support adapted to support a filter membrane is disposed in the filter retaining groove. The first housing section and the second housing section are clamped together during use.</p> |
