Pesticides or Heavy Metals in your Extracts or Oils?

Pesticide residue or heavy metal content can ruin a batch of a botanical extract, creating large problems for processors. Curated adsorbents, specifically chosen for your situation, can be used to rescue the extract. With a rotating bed reactor, you are equipped to respond to contaminants showing up on your test results.

We can help you with:

  • Myclobutanil (”myclo”; the active ingredient in Systhane®)
  • Malathion
  • Piperonyl butoxide
  • Chlorpyrifos
  • Acequinocyl
  • Spinosad
  • ... and many more!

Heavy metal traces

Many plants are effective in binding heavy metals from the soil in which they grow, and consequently the metals are found in any extracts produced from them. If the soil contains high levels of heavy metals, the resulting concentrate may be unfit for human consumption, and need remediation.

Starting with an ethanol extract of Cannabis sativa that had noticeable levels of arsenic and lead, we remediated these contaminants to non-detectable (as pure as is quantifiable) using an adsorbent that specifically binds heavy metals.

Our equipment is available in many configurations to fit any processor, also in large industrial volumes. The straightforward principle of the rotating bed reactor can be tested on your specific extract in the lab before deployed full-scale in your operations.


The RBRs offer several advantages over traditional batch reactors for extract remediation. First, the rotating bed reactor provides continuous processing, which means that the extract can be processed in real-time as it is produced, avoiding the need to store large volumes of contaminated extract. Second, the adsorbent cartridge can be replaced easily, allowing for quick changeover between batches. Third, the reactor's design ensures optimal mixing and contact between the adsorbent and the extract, leading to efficient contaminant removal.
