A sublimatory [1] [2] or sublimation apparatus is equipment, commonly laboratory glassware, for purification of compounds by selective sublimation. In principle, the operation resembles purification by distillation , except that the products do not pass through a liquid phase .
The term was later also applied to the indirect sublimation transfer printing process, which uses a standard ink-jet printer to deposit sublimation-capable ink onto a transfer sheet. The printed transfer sheet is then pressed with the substrate with heat, transferring the dye to the substrate, such as plastic or fabric, via sublimation.
In psychology, sublimation is a mature type of defense mechanism, in which socially unacceptable impulses or idealizations are transformed into socially acceptable actions or behavior, possibly resulting in a long-term conversion of the initial impulse.
The two-season Purge series takes place in the years between Anarchy and The Purge: Election Year. The show’s first season follows a group of Americans on Purge Night 2027 as they struggle to ...
The sublimation that occurs at the solid-gas boundary (critical sublimation point) (corresponding to boiling in vaporization) may be called rapid sublimation, and the substance sublimes rapidly. The words "gradual" and "rapid" have acquired special meanings in this context and no longer describe the rate of sublimation. [citation needed]
The Knudsen cell is used to measure the vapor pressures of a solid with very low vapor pressure. Such a solid forms a vapor at low pressure by sublimation.The vapor slowly effuses through the pinhole, and the loss of mass is proportional to the vapor pressure and can be used to determine this pressure.

The most straightforward type of air-free technique is the use of a glovebox. A "glove bag" uses the same idea, but is usually a poorer substitute because it is more difficult to purge, and less well sealed. Inventive ways of accessing items beyond the reach of the gloves exist, such as the use of tongs and strings.
The purge gas is inert, i.e. by definition [1] non-combustible, or more precisely, non-reactive. The most common purge gases commercially available in large quantities are nitrogen and carbon dioxide. Other inert gases, e.g. argon or helium may be used. Nitrogen and carbon dioxide are unsuitable purge gases in some applications, as these gases ...
