eDIY-sampler: an effective low-cost, compact and reproducible filtration system for aquatic eDNA sampling

Environmental DNA (eDNA) methods are now commonly used for aquatic biodiversity monitoring, yet a lack of protocol standardization and the high cost of commercial samplers hinder broader application and results comparisons. Here, we present eDIYsampler, a compact, low-cost, and reproducible filtration system for eDNA sampling. The system allows rapid field deployment, thanks to its parallel filtration system, and high compatibility with all filter types and sizes, all for <500€. The device is highly modulable and modifiable and we propose some improvements at the end.
