Frequently Asked Questions (FAQ)

Here's a tip for minimizing leftover ethanol during the evaporation process:

• Filter Lid Adjustment: While using the filter lid with its mesh screen and condenser is standard practice, you might consider removing the metal filter plate before evaporation. This modification allows for improved airflow through the condenser, reducing the chance of ethanol vapor condensing back into the beaker and becoming trapped as liquid. The leftover liquid you sometimes see is often due to ethanol condensing on the metal filter and dripping back down. Eliminating the filter plate creates a clearer pathway for vapors to travel through the condenser, promoting more efficient ethanol recovery. (You can find a video demonstration here: link to video)
