Environmental DNA, or eDNA, can be captured from waterbodies and used to detect biodiversity with the NatureMetrics aquatic eDNA sampling kits. Here, our CEO Katie Critchlow shows you how simple it is to take an eDNA sample from water.

Katie shows you how to collect a water sample, filter the water using the filtering kit provided, and preserve it with our preservative solution. After watching this video, you’ll have seen how easy the aquatic eDNA sampling process is, and you will be ready to collect your own eDNA samples using our easy-to-use kits and protocol.

Back to Aquatic Protocols



In the video below, our soil scientist Dr Hayley Craig shows you our standard protocol for collecting soil samples using the cold storage iDNAture kit.

Our soil and sediment sampling kits are easy to use in soft substrates and have been tested in terrestrial, freshwater and marine environments. Cold storage is the best way to preserve DNA in soils and sediment samples, but we recognise that this is not always possible. We therefore provide alternative means of sample preservation where required, and can help you to design a sampling methodology that meets your specific project requirements. Talk to our team to ensure you use the best kits for your project.

Back to Soils & Sediments Protocols


  • Return your samples using the box that kits were sent in, where possible.

  • If using an alternative box, ensure that it is in good condition and remove any old labels.

  • Avoid excess spacing by adding cushioning material (e.g. bubble wrap, newspaper) to avoid the product shifting inside the box.

  • Use good quality sealing tape and seal along box edges in a H pattern.

  • The only essential thing to send back to us is the specimen bag containing the filter and the sampling datasheet. However, all kit contents can be sent back to NatureMetrics for recycling.

Important considerations for your sampling

  • The absence of a detection does not necessarily imply the absence of a taxon from a location.

  • Samples from some locations might have compounds that inhibit analyses resulting in reduced data generation – while we routinely test for inhibition, it is not always possible to overcome.

  • It is the responsibility of the client to ensure that all efforts have been made to avoid contamination from external sources and between samples.

  • Handling samples without gloves can increase the content of human DNA, reducing data generation.

  • After sampling, movement of samples across borders without permission is not allowed as they are classed as biological samples.

Important considerations for interpreting your results

It should be noted that DNA can enter an ecosystem via many routes (e.g. wastewater from commercial and domestic sources). While DNA from a given taxon may be present and detectable, it is not possible to discern the source of the DNA. Results from common food items, domestic species and livestock species need to be interpreted with caution.
