Cannabis extract purification

Perfect the clarity, scent, and taste of your cannabis extract using a safe and clean technology.

Proven in Pharma, Food & beverage, and the Flavour & fragrances industries, the Rotating Bed Reactor (RBR) is a modern tool for processing liquid products. Whether it's the remediation of a contaminant, or the improvement of batch properties, the RBR offers cannabis processors greater control than ever before.

Examples of remediation tasks

  • Pesticides
  • Heavy metals
  • Color
  • Odor
  • Taste

The RBR has been great! It cuts the processing time on our 100L reactor by more than half.

Cannabis remediation


Unfavourable color, smell, or taste can be remediated using an adsorbent. This is a granular material that binds the unwanted compounds in the extract. Using the right adsorbent, you selectively take out the impurities while still leaving the desirables in the extract.

Rotating bed reactors

Our technology is a tool that uses adsorbents in a safer and more effective way. The rotating bed reactor utilizes the adsorbent to its full potential, offering better performance than traditional methods. Expect to see improved clarity and substantially streamlined operations.


The rotating bed reactor is filled with adsorbent, spun in the extract until the target has been reached, and finally emptied of the spent material. The adsorbent is conveniently deployed in bags, removing any hassle associated with the handling of powders.

Application 1008
Activated carbon decolorization, fast and without filtration

Activated carbon is a common choice for removing impurities or capturing compounds from a product batch. However, the carbon may itself foul the product and be difficult to separate. The rotating bed reactor offers a clean way to deploy activated carbon that removes the need for time-consuming filtration and extends the lifetime of the solid phase.

Application 1030
Viscous solutions decolourized using a rotating bed reactor and a stirred tank reactor

Decolorization, pesticide remediation, catalysis, and many other applications involve dealing with viscous liquid that needs to be modified in some way. The rotating bed reactor presents an efficient way to treat viscous liquids, without the challenges of conventional reactors.

Application 1045
Pesticide remediation in extracts and oils

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

Application 1044
Simple scale-up using flexible reactors

Research and development quickly takes new directions, and the requirements on a laboratory may vary with every new project. Limiting yourself to equipment with a narrow scope of conditions and applications may become expensive, since new equipment must be acquired for anything out of scope. With budgets quickly consumed by other projects, the need for new equipment may mean significant delays and a reduced capability to take on emerging opportunities.

Application 1048
Heavy metal remediation in extracts and oils

Plants accumulate 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.
