Abstract
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.
