Hence they are not appropriate for storing chemicals which react quickly or violently with atmospheric moisture such as the alkali metals; a glovebox or Schlenk-type apparatus may be more suitable for these purposes. Desiccators are sometimes used to remove traces of water from an almost-dry sample.
The collected water molecules are transported from leaf surfaces to an internal storage network via osmotic pressure with capacity sufficient for the plant's growing requirements. [ 1 ] The file snake ( Acrochordus granulatus ), from a family known as completely aquatic, has hygroscopic skin that serves as a water reservoir, retarding ...
A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant. Commonly encountered pre-packaged desiccants are solids that absorb water. Desiccants for specialized purposes may be in forms other than solid, and may work through other principles, such ...

Screw-on water-purifying filters. Stainless-steel collapsible-handle cups, for drinking and/or stove-top cooking, that store compactly with a Nalgene litre-bottle nested inside them. Insulated Nylon-fabric cases for Nalgene 1-litre bottles; features include stable attachment points and, in most cases, nesting for a cup.
In chemical processing industries like food processing, pharmacology, agriculture, and textiles, drying is an essential unit operation to remove moisture. [1] Vacuum drying is generally used for the drying of substances that are hygroscopic and heat-sensitive, and is based on the principle of creating a vacuum to decrease the chamber pressure ...
Ampoules containing pharmaceutical products A large ampoule containing 1.4 kg (3.1 lb) of high-purity caesium. An ampoule (also ampul and ampule) is a small sealed vial which is used to contain and preserve a sample, usually a solid or liquid.
The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Many of them are hygroscopic . Organic compounds
