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 ...
List of desiccants: [1]. Activated alumina; Aerogel; Benzophenone (as anion); Bentonite clay; Calcium chloride; Calcium hydride; Calcium oxide; Calcium sulfate ...
A vacuum desiccator (left) and desiccator (right). Silica gel with cobalt chloride indicator placed in the lower shelf is used as the desiccant.. A desiccator is a heavy glass or plastic container, now somewhat antiquated, used in practical chemistry for drying or keeping small amounts of materials very dry.
Contact herbicides used for desiccation include: carfentrazone-ethyl, cyclanilide, diquat, endothall, glufosinate, paraquat, pelargonic acid / ammonium nonanoate, pyraflufen-ethyl, saflufenacil, sodium chlorate, thidiazuron, and tribufos. [1] [5] [4] [7] [11] The most common and widely used contact desiccant is diquat (Reglone).
Silica xerogel with an average pore size of 2.4 nanometers has a strong affinity for water molecules and is widely used as a desiccant. It is hard and translucent , but considerably softer than massive silica glass or quartz , and remains hard when saturated with water.
They are often used in industry to achieve humidity levels below 35%. Because of the absence of compressor parts, desiccant dehumidifiers are often lighter and quieter than compressor dehumidifiers. Desiccant dehumidifiers can operate at lower temperatures as the unit does not need cooled coils.
The Eargo app is simple to use and can easily find the optimal hearing profile for your environment, whether outdoors, indoors, or at a noisy gathering. ... you can use a dry-aid kit, a desiccant ...
In laboratory use, the most common desiccators are circular and made of heavy glass. There is usually a removable platform on which the items to be stored are placed. The desiccant, usually an otherwise-inert solid such as silica gel, fills the space under the platform. Colour changing silica may be used to indicate when it should be refreshed.
