eDNA SAMPLER
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
