A rectification lens is a reflux condenser that increases the strength of the distillate by returning to the boiler the reflux resulting from the cooling of alcohol vapors, this is achieved by supplying cold water to the upper part of the lens. The lens is easy to use and can be easily attached to the apparatus by means of a threaded connection. The lens consists of 99% copper, and copper perfectly conducts heat, therefore, it provides uniform and fast heating. In addition, it effectively adsorbs sulfur, preventing it from entering the finished product. The distillate will retain the pleasant aroma and taste of the feedstock. The lens is connected to the alambic by means of a thread and a nut, so it will fit any device (of the corresponding volume) with a thread on the dome.

The lens traps the water from the distillation, increasing the alcohol content by 20-30%
