eDNA Filters

Get better results with our preloaded inline filters for eDNA sampling.

Self-preserving eDNA Filter Packs

Reduced Chance of Sample Contamination

Alternate sampling methods require removal of the filter in the field for preservation. Any handling method will increase the chance of contamination. With the self-preserving filter housing, the filter is never handled until safely back in the laboratory giving you increased confidence in your research.

Higher DNA Yields

Research demonstrated almost twice the yield of DNA per liter when using self-preserving filter housings compared to the standard methods using ethanol. Easier to use and improved science!

No More Ethanol

Preparing to go in the field is time consuming. With the self-preserving filter housing, you no longer need to prepare vials of ethanol for the field. Not to mention, you just lightened your load by leaving the ethanol behind.

Additional benefits

  • Reduced waste
  • Biodegradable
  • Reduced field time

Single Use eDNA Filter Packs

  • Preloaded and individually packaged (reduces chance of sample contamination)
  • Engineered to create higher DNA yield per liter of water
  • Packet containins a preloaded inline filter, forceps, and tubing extension

Typical eDNA filtering utilizes gravity and/or a uniform cylinder shape. Both of these design flaws contribute to increased clogging of the filter with sediment and non-target particulates. The specially engineered cone on our eDNA filter housing optimizes the capture of cellular material and reduces the capture of unwanted materials.

Compatible with eDNA Sampler or your own sampling system.

Available in multiple filter sizes.

Satisfaction Guaranteed Smith-Root eDNA filters are covered by our exceptional warranty service. If the filter does not perform within specifications (e.g. air leakage < 12 psi) we will replace the filters at no charge to you within one year of purchase. Guarantee applies to appropriate use of the filters with the Smith-Root eDNA Sampler system or approved pump. Note: Small, slow-moving bubbles in the suction tubing may occur at high pressures (> 10 psi) and are caused by dissolved gases coming out of solution under vacuum pressure. This is normal and does not indicate leaking. Large, fast-moving air bubbles should not be observed under normal circumstances. Please contact Smith-Root technical support if you have questions.
