The aroma compounds are then mixed back into the wine. Some producers such as Joel Peterson of Ravenswood argue that technological "fixes" such as spinning cones remove a sense of terroir from the wine; if the wine has the tannins and other components to balance 15% alcohol, Peterson argues that it should be accepted on its own terms.

Most markers have alcohol-based solvents. Other types, called paint markers, contain volatile organic compounds which evaporate to dry the ink, and are similar to spray paint . Due to solvents such as toluene and xylene often being present in permanent markers, they have a potential for abuse as a recreational drug .
Ballpoint pen: Société Bic: Used generically in colloquial British, Irish and Australian English, particularly for cheaper disposable pens, but remains a registered trademark. Derived from the name of the inventor, László Bíró. [65] Bobcat Skid-steer loader: Bobcat Company: This usage is especially common in Australia.
A rotary evaporator [1] (rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was evaporated ...
Extractive distillation is more costly than ordinary fractional distillation due to costs associated with the recovery of the separating agent. One advantage of salt-effect distillation over other types of azeotropic distillation is the potential for reduced costs associated with energy usage.
Alembics from a 1606 alchemy book. Dioscorides's ambix, described in his De materia medica (c. 50 C.E.), is a helmet-shaped lid for gathering condensed mercury. For Athenaeus (c. 225 C.E.) it is a bottle or flask.
Phase diagram (left) and process flow diagram (right) of an apparatus for the azeotropic distillation with "material separation agent". In this case the phase diagram includes a zone where components are not miscible, so following the condensation of the azeotrope, it is possible to separate the liquid components through decantation.
Correction fluid bottle Correction fluid bottle Correction pen. A correction fluid (or correction liquid) is an opaque, usually white fluid applied to paper to mask errors in text. Once dried, it can be handwritten or handdrawn upon.
