The water bath temperature should not exceed the boiling point of the solvent! • The condenser could be overloaded since the evaporation rate will exceed the condensation capacity. Cannabis extracts require lower water bath temperatures (≈40 degrees Celsius). Oil baths can hold a higher temperature range than water baths.
