Abstract
This invention relates to a filtration apparatus and method for the separation of microscopic entities from a fluid (liquid or gas) and subsequent visual or imaging microscopic analysis of the entities separated thereon either directly or after treatment of the entities whilst on the apparatus in order to enhance their subsequent visualization and/or imaging. Such treatment can comprise reaction with reagents contained in other solutions that can be made to imbibe and/or pass through the filtration apparatus and which can be washed with solutions that can be made to imbibe and/or pass through the filtration apparatus. An example of a specific area of application is in the microbiological testing of fluids in order to detect, identify and/or enumerate microorganisms contained in a fluid test sample.
