Environmental DNA (eDNA) is not evenly distributed in water. Its concentration varies between locations, depending on the distribution of organisms, water movement and local environmental conditions. A well-designed eDNA sampling strategy is therefore crucial to successful eDNA analysis.

At Sylphium we apply a standardised sampling approach that is based on existing guidelines and published research. Our method involves collecting spatially distributed subsamples and combining them into composite samples. The sampling effort is adapted to the size, characteristics, and habitat diversity of each waterbody.

Additionally, we provide sampling materials that are devloped in line with the NPR 7394 guidelines, enabling rapid and highly reliable sample collection.

Complete eDNA sampling set

Sylphium’s SYL009 Complete eDNA sampling set enables active collection and on-site filtration of water samples, minimizing contamination risk while keeping fieldwork lightweight. The set includes an eDNA Dual Filter and a 60 mL syringe. Attach the filter unit to the syringe and press water through the unit. A vacuum pump is not required. A

fter adding preservation fluid and sealing the unit with the supplied caps, the sample remains stable for weeks to months without refrigeration. Each sampling set arries a unique sample number for secure identification and can be shipped unrefrigerated to our lab. eDNA sampling sets can be ordered here.
