Q: We are working with CBD and cannabis resin in our lab and the residue is very tough to remove. We are currently using isopropyl alcohol and it is just not good enough. Any advice?
A: It is no secret that waxy, sticky cannabis and hemp residue, and other botanical resins are some of the most difficult residues to clean. But of course, keeping your labware, glassware and other laboratory equipment clean is vital. This ensures your cannabis, cannabinoid (CBD) or other botanical product is of the highest purity, and your parts and instruments are clean and clear. Critically clean to be specific.
For the laboratory setting, we would recommend the following detergents for soaking, scrubbing or sonciation (ultrasonic) of your parts:
The Alconox detergent is a powder, while the Detonox cleaner is a liquid concentrate. The latter is more potent and is best for the tough residues in your lab. For a phosphate-free option, Liquinox® Critical Cleaning Liquid Detergent is a fantastic choice.
We would recommend warm to high heat temperatures (140F/60C+) and a 2-3% concentration for starters. Initial rinse should also be warm to avoid thermal shock of micelles that form. Subsequent rinses can be at ambient temperatures.
If your lab has a conventional under the sink washer which you intend to use, we would go with Alcojet® Low Foaming Powdered Detergent. For larger scale, liquid dispensing washer, please see our TechNotes article on cannabis and botanical processing.
