eDNA Sampler
Autonomous eDNA Multi-sampling for the Detection of Biological Genomic Signatures in Water
eDNA Sampler: Automated sample collection
The DOT eDNA Sampler is designed to offer autonomous in situ sample collection The eDNA Sampler is:-
- Self Priming.
- Self Cleaning.
- Self Preserving.
The DOT eDNA sampler is designed for remote, long-term eDNA sample collection in locations that are difficult to reach and maintain
via vessel and service technician. Samples can be scheduled by date and time, triggered by depth/pressure, or configured to be triggered by a 3rd party sensor/device via RS-232 serial data connection. The self-cleaning and preserving functions dramatically reduce cross-contamination between each of the sample filters. The quick-change filter cassettes hold nine DNA filters each and the eDNA Sampler can hold enough reagent chemistry to clean and preserve three cassettes (or 27 DNA filters). Reagents are held, stored, and deployed onboard the sampler.
DOT-NM Sampler: For NatureMetrics DNA filters
In 2023 Dartmouth Ocean Technologies signed a partnership with Naturemetrics in the UK. The basis of which is very simple:-
- DOT provides ocean ready eDNA sample collecting hardware.
- NatureMetrics provides world class eDNA Lab analysis (after the samples have been retrieved)
Developed with Dartmouth Ocean Technologies, the DOT-NM Autosampler helps organisations overcome limitations to comprehensive biodiversity sampling, including reducing vessel and labour fees.
Operating the Autosampler is easy. It can be integrated with drones, launched from ports, vessels, and offshore platforms and customized to meet a broad range of requirements.
Combine autonomous sampling, with world-class eDNA analysis and automated analytics pipelines to rapidly generate holistic insights of aquatic ecosystems without requiring large field teams and data scientists.

eDNA Rapid Sampler: High Volume sample collection
The eDNA Rapid Sampler has replaced the need for self-cleaning and preservation with the ability to collect much larger DNA Sample volumes.
At up to 600 mL per minute, the rapid sampler can collect 10x the eDNA sample volumes (per filter) of the original eDNA Sampler in a fraction of the time.
Based on a filter-first concept of operation, the rapid sampler offers nine pumps for nine DNA filters.
Giving each DNA filter its own dedicated pump allows for parallel sample collection. The Rapid sampler can be triggered to collect single, dual, or triplicate samples at the same time and/or from the same location. Removing the onboard reagents has resulted in a more compact design suitable for a range of remote and autonomous vehicle payload bays. Communication and control have also been improved for the eDNA Rapid Sampler, now offering RS-232, RS-485, and Ethernet communication to the user.
Watch Hakai Institute’s The Nature Files documentary, “The Case of the Wayward Whales”, showcasing the eDNA Sampler in use during an Arctic research mission to track whale migration.
