Fixation filter assembly
Abstract:
A filter assembly is provided for collecting samples in a fluid environment, the assembly utilizing a laminar convective flow to cause the flow of a preservative/fixative and a filtrate through a filter. A substantially concave dead space around the filter is flushed free of the preservative and the differential in density of the preservative and filtrate causes the more dense fluid to collect in the reservoir and preserve the collected specimen.
