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 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 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.

A heat press is used to permanently apply a heat transfer to a surface. Common transfer types are Heat Transfer Vinyl cut with a vinyl cutter, Printable Heat Transfer Vinyl, Inkjet Transfer Paper, Laser Transfer Paper, Plastisol Transfers, and Sublimation. Using a Heat Press to apply a heat transfer is a way to ensure accurate time, temperature ...
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.
None of this came without warning. Among Musk’s friends in Silicon Valley, many understood his takeover of Twitter as preparation for a greater cause.
After the digital design is printed onto sublimation transfer sheets, it is placed on a heat press along with the substrate to be sublimated. [ citation needed ] In order to transfer the image from the paper to the substrate, it requires a heat press process that is a combination of time, temperature and pressure.
