A filtration assembly (10) for use in culturing microorganisms includes a sample reservoir (20) for holding a fluid to be filtered, a base (30) which can be engaged with a lower end of the sample reservoir to support a filter element (45) during filtration, and a cover assembly (50) for covering an upper end of the sample reservoir. The cover assembly is capable of being used as a petri dish by itself, or a portion of the cover assembly (70) can be combined with the base (30) to form a petri dish.
