Filtration sampling methods

Abstract

A method for testing a liquid specimen sample is provided, the method including placing the liquid specimen sample in a tubular container of a filtration assembly of a sampling device. Thereafter, the liquid specimen sample is brought into contact with a filter removably disposed on a support surface defined by a filter support of the filtration assembly, while a filter-withdrawal shaft of the sampling device is coupled to the filter. Thereafter, at least a portion of the liquid specimen sample is driven through the filter and a plurality of filtrate-passage openings defined by the filter support. The filter-withdrawal shaft is withdrawn from the filtration assembly, thereby removing the filter from the support surface and from the filtration assembly, while leaving the filter support within the filtration assembly. Thereafter, the filter is tested for the presence of biological particulate trapped by the filter. Other embodiments are also described.
