Looking to get your butane or propane extraction equipment down to cryogenic temperatures without paying the ticket for a powerful mechanical chiller? Look no further, we have your solution. Dry ice material columns use the chilling power of dry ice in a jacketed sleeve to cool your material / solvent wash to temperatures that don't pull fats, lipids, and chlorophyll which protects the quality of your extraction.
