An apparatus for collecting and storing fluid samples from vehicles and machinery comprises a storage container having a fluid inlet sealed by a cap, the cap having an aperture releasably sealed by a lid. An adapter connects the cap releasably to a fluid outlet coupling port of a fluid sampling device. The adapter comprises a lumen, having an inlet and an outlet aperture, an external screw thread engageable with an internal screw thread of the coupling port and a connector assembly for connecting the adapter releasably to the cap. A penetrable diaphragm provides an airtight seal over a storage region of the storage container. When the adapter is connected to the coupling port and the cap is connected to the adapter, a fluid outlet tube extending from the coupling port extends through the aperture and protrudes through one or more perforations provided in the penetrable diaphragm into the storage region.

An inline filter housing with a biodegradable, hydrophilic material that operates in conjunction with a field sampling apparatus to both concentrate field sampled environmental DNA particles from water samples and to automatically preserve the captured DNA via desiccation, thus avoiding filter membrane transfer steps, chemicals or cold storage preservation requirements. The hydrophilic filter housing is capable of rapidly preserving the field sampled environmental DNA captured on the filter membrane at ambient field temperatures.
