This may be the last Ethyl Wash prior to Supercritical Drying. I tested the Ethyl from Wash #2, and it measured @ 198 Proof (99%). This next wash is starting at 199.5 Proof (99.75%), so depending on the amount of H2O left in the gels, that will only drop a minute fraction. Wash #4 may be necessary, but most likely it will be Overkill.
I need to set aside cash for Ice, CO2, Propane, and Dr. Pepper. $200 will serve.
