AcSample and DiP-FAST: low-cost samplers from Acbotics Research

For many water and eDNA sampling applications, simple is good enough, so we sought to develop accessible and affordable rapid sampling options for riverine and coastal applications. The two technologies that resulted are the DiP-FAST (Differential Pressure Filtered Accumulating Sample Tube) and AcSample systems. The DiP-FAST is all mechanical, the simplest solution we could come up with to a filter-agnostic, inexpensive eDNA sampler device. The AcSample provides a triplicate pumped solution, with three independent filter/pump/flow sensor manifolds and pressure/temperature logging. Both systems are designed for easy negative control, and include filter-agnostic luer lock attachments on the outside for simplicity and to reduce cross-contamination. Once sampling is complete, preserve your filter as desired, swap in a new filter, and re-deploy.
