(b) a fluid port in fluid communication with the sample reservoir;
(c) a porous microorganism-capturing filter element disposed across a flow path between the sample reservoir and the fluid port, the porous microorganism-capturing filter element being releasably retained by the at least two inwardly facing arms;
(d) an absorbent pad arranged below the porous microorganism-capturing filter element and the at least two inwardly facing arms, disposed across the flow path between the sample reservoir and the fluid port;
(e) a base detachably mounted to the sample reservoir, the base including the fluid port, and a support surface for supporting the absorbent pad;
