Ascension | Environmental DNA Depth Sampling Technology

Deploy by hand from a small boat down to 400-meter depths

Pre-program and attach to a fixed installation for automated sampling

Collect up to 7 separate samples per deployment or include replicates for every deployment

Eliminate sample contamination risks with in-situ filtration

Capture real-time depth, salinity, temperature, flow rate and total volume data every second

Recharge the battery within 2-3 hours using a standard wall outlet

Make on-the-fly changes during your deployment with an easy-to-use computer interface

"You can just go out with the Ascension device and sample quite easily on the tender itself. It opens a lot more doors for end users to implement eDNA into their (biodiversity) monitoring.”

“Ascension took away a barrier for the skills needed for sampling. It is foolproof compared to other equipment. I was really excited. I can’t believe the data we’ll get!"

“The best place to look for information is going to be at depth. Ascension is really one of the only ways that we can get our hands on those deeper samples given the platforms of opportunity available to us for this project.”
