I have seen the predominance of two type of dewaxing with a CLS. The first involves drying the material to less than 10% humidity. Then filling the column and freezing the whole kit & caboodle for at least 24 hours. At processing time, the column is removed from the freezer and immediately filled with dry ice in the column jacket. There seems to be a lot of question to soak or not to soak. Community input would be greatly appreciated. The other predominate method involves a separate material column before the dewaxing column and an extensive 60-90 min soak using dry ice and solvent bath in the column. I would like to hear from community members about their experiences & preferences and why they feel that way; pro and con. Thanks for your time.
