The innovative self-preserving filters are designed to maximize DNA yield per liter of water while enabling automatic preservation through desiccation. Simply return the filter to its original packaging—no additional reagents required.
Available in multiple pore sizes and materials, these filters allow you to customize your setup to fit your project needs. Each pack includes a preloaded inline filter, forceps, and a tubing extension, ensuring seamless integration with Smith-Root samplers or your own sampling system.
For deeper water sampling, a specialized adapter connects the filter housing directly to a Niskin bottle, enabling immediate filtration of collected samples for eDNA analysis. Backed by extensive scientific research, Smith-Root eDNA filter packs offer a reliable and efficient solution for your sampling needs.

eQuip sampling system & filter kits
This original underwater sampling system was developed by Sequench with support from the Callaghan Innovation R&D fund. It allows concentrating waterborne eDNA without onboard pumps. Our patent-pending design uses a Venturi-based suction system: a narrow throat followed by up to three perimeter sampling openings. The pressure differential created by the Venturi effect enhances water intake and ensures consistent flow through the filter units mounted on each intake.
Explore eQuip products and specifications here:
eQuip underwater sampler operates at cruising speeds up to 12 knots, delivering ~5–12 L/min per intake (speed-dependent) for high-volume eDNA capture and clean field workflows. Its teardrop hydrodynamic body minimises drag, while inverted planform lateral wings and directional fins keep the unit stable and on course during tow. The filter units are mounted onto outer parts of different sample collection systems with minimal handling interference, thus minimizing risk of contamination.
Proven on small motorboats, sailing yachts, and oceanographic vessels across lakes, coastal waters, and open ocean. With a weight depressor, the system can be submerged and towed to ~30 m depth.
Recommended towing speed: 6-12 knots
Approximate sampling depth: 1-2 m (depending on the speed and point of attachment)
Drag: 14 N (6 knots), 26 N (8 knots), 40 N (10 knots)
Modeled sample volume: 5-12 L/min (depending on the speed and sea conditions)
Attachment: Metal swivel (enclosed) for rope connection (not provided)
Size: 380 mm x 260 mm x 13 mm
Weight: 2 kg
Other possible operating modes: passively deployed at high-flow environments, attached to a ROV or AUV, attached to a water pumping device

The filter kit consists of individually packed universal filter membrane holders made of recycled biomass-based plastic (PLA), designed to accommodate standard 47 mm diameter filter membranes. The inner ring securely holds the membrane during sampling and can be easily detached from the base by flipping the lip, allowing the membrane to be isolated for downstream analysis without excessive handling. The lip on the base also serves as a handle, enabling straightforward insertion and retrieval of the filter from packaging and sampling devices.
For sampling, filter units are removed from the pouch, inserted into the sample mounts, and deployed at 6–12 knots for 5–10 minutes, depending on sampling requirements. Following retrieval, the filter unit is removed using the holding lip, excess water is shaken off, and the unit is returned to the desiccation pouch for storage until processing, or the membrane can be transferred directly into a tube containing preservation buffer. The storage bag should be securely sealed to ensure effective preservation. If freezing is the preferred method, the filter unit can be stored directly in the sealed bag at −20 °C.
For enhanced preservation, particularly when extended storage prior to laboratory processing is expected, or when targeting low-abundance or potentially degraded eDNA signals (e.g. fish or other vertebrates), a buffer spray option is available. This approach has been validated through extensive field trials. The buffer is supplied in a 10 mL spray bottle (sufficient for approximately 25 filters), with four sprays applied directly onto the membrane immediately after retrieval and prior to placement into the desiccation pouch.
