What is Molecular Distillation?

principle diagram of the molecular distillation
Molecular distillation (Short Path Distillation) is a special kind of liquid - liquid separation technology. It is different from steam distillation, which relies on the separation principle of difference of boiling point. While Molecular distillation relies on the difference of the average free path of molecular movement of different substances to achieve separation.

Lab1st Wiped Film (Molecular) Distillation Unit

Molecular distillation equipment or short path distillation equipment is very efficient for hemp distillation. At Lab1st, we offer you different model of Wiped Film Molecular Distillation Unit for dab, shatter, hemp, and other forms.

Material is delivered from a feed flask into a columniform evaporation section, getting heating, on the outside, (circulating hot fluid jacket type), and a slotted wiper mechanism forcing liquid around and downward in a thin film on the inside. In the center of the body is a wiped film evaporator with internal cooling condenser, providing a short path for vapor molecules traveling from the heated surface to the condenser surface. For cannabinoids, the internal condenser fluid must be kept elevated (~80°C) to prevent high viscosity or freeze up cbd distillate and the related components. During the itinerary downward, lighter (lower boiling point) fractions of the liquid begin to vaporize, move to the internal condenser and condense, falling down as a liquid into a vessel that catches and separates the distilled liquid (cannabinoid) which flows into a receiver flask. Heavier residue material (chlorophyll, salts, sugars, heavy wax fractions) does not evaporate and instead travels through the still body and flows into a different receiver flask.
