Evaporators for use with acids and essential oils
Thymol crystals can be evaporated from the solid (sublimed). Various types of Thymol frame are detailed under the link... Special Frames.
Acetic acid at high strengths is used to fumigate combs that are not in use. It has been used at the strength of a condiment in a "vinegar fogger", but as yet I have no information or experiance of this method of use.
