eDNA Rapid Sampler - Environmental DNA Sampling

eDNA Rapid Sampler - Swift eDNA Sampling

The DOT Rapid eDNA Sampler is a compact, deployable solution for aquatic environmental DNA sampling in the field. Designed for teams that need reliable eDNA collection without fixed infrastructure, it captures genetic material shed by aquatic organisms into the water column – enabling biodiversity assessment and species detection without netting, capture, or direct observation.

Autonomous, Fast eDNA Multi-sampling for the Detection of Biological Genomic Signatures in Water

The DOT eDNA Rapid Sampler is designed for high-volume marine eDNA sampling where speed and sample quantity matter. It delivers up to ten times the sample volume of traditional eDNA samplers in a fraction of the time – making it well-suited to survey operations, mobile platform deployment, and programmes where rapid, repeatable sampling is a priority.

Multi-sample eDNA Collection at Speed

With a maximum flow rate of 600 mL per minute and nine dedicated pumps serving nine individual DNA filters, the Rapid Sampler is built for throughput. Single, dual, or triplicate samples can be collected simultaneously, allowing for parallel sampling from the same location. Typical sample volumes of 1L, 5L, 10L, and 20L can be achieved in minutes, with volumes user-definable to suit programme requirements.

The compact, reagent-free design makes the Rapid Sampler compatible with a range of deployment platforms, including ROV and AUV payload bays, as well as vessel-based operations. Communication and control options include RS-232, RS-485, and Ethernet, supporting straightforward integration with wider vehicle or monitoring systems.

Onboard flow rate logging provides an additional data layer for quality assurance and programme reporting.

Environmental Monitoring Applications

The DOT eDNA Rapid Sampler supports a wide range of environmental DNA monitoring programmes across marine and offshore environments:

Biodiversity monitoring
Including Marine Protected Areas, offshore survey, wind farm monitoring, marine mammal detection, aquaculture, and invasive species programmes.

Targeted organism surveillance
Monitoring for harmful algal species such as Alexandrium, parasites or pathogens, indicator species, and general biodiversity surveys.

Downstream molecular analysis
DNA extracted from sampler filters is compatible with methods including qPCR and metabarcoding for detailed genetic analysis.
