A common use for desiccators is to protect chemicals which are hygroscopic or which react with water from humidity. The contents of desiccators are exposed to atmospheric moisture whenever the desiccators are opened. It also requires some time to achieve a low humidity.
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 ...
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 ...
Bottled water, believe it or not, isn't held to the same standards as tap water. That means harmful chemicals can leach from the bottle, especially if it’s stored for a long time, or exposed to ...
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.
The chemicals added to plastics are likely contributing more than $250 billion to annual healthcare costs in the United States, researchers say.
In addition, chemical compatibility refers to the container material being acceptable to store the chemical or for a tool or object that comes in contact with a chemical to not degrade. For example, when stirring a chemical, the stirrer must be stable in the chemical that is being stirred. Many companies publish chemical resistance charts.
