In recent years, the chemistry set has been re-imagined as a self-study kit, typically offering students better equipment and more explanatory tutorial content. For example, Thames & Kosmos offers a range of CHEM series chemistry sets targeting older children, culminating in the C3000 Kit, which includes a 172-page manual describing 387 ...

"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.
Flat-bottomed flask: A flask with similar uses as the round-bottom flask, but with a flat bottom that allows it to stand on a level surface.; Florence flask: A flask similar to the flat-bottomed flask that has round bodies and either a round bottom or a flat bottom so that one can stand the flask on a level surface.
3D model used for teaching geometry. Instructional materials, also known as teaching materials, learning materials, or teaching/learning materials (TLM), [1] are any collection of materials including animate and inanimate objects and human and non-human resources that a teacher may use in teaching and learning situations to help achieve desired learning objectives.
This equipment can be used in cases other than simple removal of water. One example is the esterification of butanol with acetic acid catalyzed by sulfuric acid . The vapor contains 63% ester, 29% water and 8% alcohol at reflux temperature and the organic layer in the trap contains 86% ester, 11% alcohol and 3% water which is reintroduced.
Crucible tongs are used most often with crucibles, small ceramic or metal vessels used to heat chemicals to temperatures up to 565.56 degree Celsius. [3]As a crucible will be very hot when heating it in a furnace or a Bunsen burner, one cannot hold the crucible directly.
