    en.wikipedia.org/wiki/Kugelrohr

    "Short path" refers to the short distance that the vapors of the distillate need to travel, which helps reduce loss and speed up collection of the distillate.This type of distillation is generally performed under vacuum to prevent the compound from charring due to atmospheric oxygen, as well as to allow the distillation to proceed at a lower temperature.

  3. Retort - Wikipedia

    en.wikipedia.org/wiki/Retort

    In a chemistry laboratory, a retort is a device used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated.

  4. Dry distillation - Wikipedia

    en.wikipedia.org/wiki/Dry_distillation

    Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). The method may involve pyrolysis or thermolysis, or it may not (for instance, a simple mixture of ice and glass could be separated without breaking any chemical bonds, but organic matter contains a greater diversity of molecules, some of which are likely to break).

    en.wikipedia.org/wiki/Distillation

    Dry distillation (thermolysis and pyrolysis) is the heating of solid materials to produce gases that condense either into fluid products or into solid products. The term dry distillation includes the separation processes of destructive distillation and of chemical cracking, breaking down large hydrocarbon molecules into smaller hydrocarbon ...

  6. Condenser (laboratory) - Wikipedia

    en.wikipedia.org/wiki/Condenser_(laboratory)

    In distillation, a mixture is heated until the more volatile components boil off, the vapors are condensed, and collected in a separate container. In reflux, a reaction involving volatile liquids is carried out at their boiling point, to speed it up; and the vapors that inevitably come off are condensed and returned to the reaction vessel.

  7. Coking factory - Wikipedia

    en.wikipedia.org/wiki/Coking_factory

    A coking factory or a coking plant is where coke and manufactured gas are synthesized from coal using a dry distillation process. The volatile components of the pyrolyzed coal, released by heating to a temperature of between 900°C and 1,400 °C, are generally drawn off and recovered. There are also coking plants where the released components ...

    en.wikipedia.org/wiki/Vapor-compression_evaporation

    Vapor compression distiller made by BRAM-COR (Italy) Vapor-compression evaporation is the evaporation method by which a blower, compressor or jet ejector is used to compress, and thus, increase the pressure of the vapor produced.

    A marijuana vending machine is a vending machine for selling or dispensing cannabis. They are currently in use in the United States [1] and Canada [2] [3] and some may be located in secure rooms in marijuana dispensaries.
