Environmental DNA Sampling

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

  • Automatic operation according to a preconfigured mission profile
  • Micro-fluidic architecture reduces reagent usage and facilitates storage of waste products for later disposal
  • Sample preservation via RNAlater enables long-term, unsupervised deployment
  • Customize based on the filter material needed (ie. PC, PVDF)
  • Optional: Integrated 4-channel fluorometer (Chl-a, PC, PE, FDOM)
  • Compact design allows for deployment from a variety of vessels and platforms

Multi-sample eDNA Collection Made Easy

eDNA sampling is a valuable tool for studying both prokaryotic and eukaryotic biodiversity in the water column.​  Dartmouth Ocean Technologies has developed a portable, convenient solution for use in many data collection scenarios.

The programmable nature of the instrument allows for increased sampling resolution over long periods of time – ideal for time series studies​.

DNA can be extracted from filters using various commercial kits (ie. Qiagen, BioMeme)​. The integrated multi-sample holder makes transporting the samples more convenient.

Environmental Monitoring

  • Commissioning and decommissioning of various coastal and offshore work sites​
    • Oil and Gas
    • Wind farms
    • Aquaculture
  • Monitoring the environment for specific organisms of interest
    • Harmful algae (ie. Alexandrium sp.)
    • Parasites or pathogens
    • Indicator species
  • DNA extracted from the sampler filters can be further processed with methods such as qPCR​
