Recently we ran a bunch of trim that passed state testing for pesticides. Turns out the detection level at the lab was not low enough to detect the small amount of pesticides that was in the trim. As you can guess once we extracted it the product failed.
Which leads me to our current problem, the recovery pump. We have already trashed all the butane in the solvent tank and dismantled the entire loop. Everything is soaking in ethanol overnight and then cleaned with a lab safe micro fiber cloth.
I am worried now about our CMEP-OL pump being contaminated with pesticides. Does anyone have insight on this, or a way to clean the recovery pump? I do not want to take any chances on having our next batches fail.
Even material that “passes” once concentrated it compounds the small amount of pesticides you said you knew where already in there. The pump shouldnt have anything to do with it
