For those of you asking about the carbon scrub SOP, I follow the Instructions from ColumboLabs and I basically only use CBleach now.
After full winterization,
- In a well ventilated area or fume hood, heat alcohol/oleoresin suspension to 80c (Just above the boiling point of ethanol and isopropanol).
- Measure 5% of total material volume in CBleach and slowly add to boiling suspension. (1000g oleoresin : 50g CBleach)
- Stir for 10-15 minutes while maintaining a minimum of 60C temperature.
- Allow solution to cool to approximately 40c and filter through silica over filter funnel
