A copper retort A glass 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.
Pot still distillation gives an incomplete separation, but this can be desirable for the flavor of some distilled beverages. If a purer distillate is desired, a reflux still is the most common solution. Reflux stills incorporate a fractionating column, commonly created by filling copper vessels with glass beads to maximize available surface ...
It also provides distillation columns to obtain mainly Armagnac and single-distilled alcohols in continuous production. Chalvignac also designs and produces high-technology equipment to set and supervise the distillation process, including gas/steam supply setting, distillate casting (heads, "brouillis" or hearts, and tails), and temperature ...
The term "fire copper" originated from the "brewing copper" or "wort copper" kettles used for brewing. Before the 19th century most distillation was performed from a simple pot still developed in 800 AD by the Arab alchemist Jabir ibn Hayyan .
Pot stills at the Lagavulin Distillery. A pot still is a type of distillation apparatus or still used to distill liquors such as whisky or brandy.In modern (post-1850s) practice, they are not used to produce rectified spirit, because they do not separate congeners from ethanol as effectively as other distillation methods.
A simple short path vacuum distillation apparatus can be used for bulb-to-bulb distillation. 1: Still pot with stirrer bar/anti-bumping granules 2: Cold finger - Condenser with maximum surface to condense most of the vapour. 3: Cooling water outlet 4: cooling water inlet 5: Vacuum Adapter 6: Receiving Flask.
More and more people are talking about polyphasic sleep patterns. But a sleep doctor explains why polyphasic sleep is so unhealthy for humans.
A larger surface area allows more cycles, improving separation. This is the rationale for a Vigreux column or a packed fractionating column. Spinning band distillation achieves the same outcome by using a rotating band within the column to force the rising vapors and descending condensate into close contact, achieving equilibrium more quickly.
