Canisters are commonly filled with silica gel and other molecular sieves as desiccants in drug containers to keep contents dry Silica gel in a sachet or porous packet. 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.
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. The material is placed on a shelf, and a drying agent or desiccant , such as dry silica gel or anhydrous sodium hydroxide , is placed below the shelf.
Drying agent may refer to: Desiccant, which absorbs water or moisture from its vicinity; Oil drying agent, which speed up the hardening of oils, often used in painting
Silica gel's high specific surface area—around 750–800 m 2 /g (230,000–240,000 sq ft/oz) [6] —allows it to adsorb water readily, making it useful as a desiccant (drying agent). Silica gel is often described as "absorbing" moisture, which may be appropriate when the gel's microscopic structure is ignored, as in silica gel packs or other ...
CaH 2 is thus used as a drying agent, i.e. a desiccant. [2] CaH 2 is a saline hydride, meaning that its structure is salt-like. The alkali metals and the alkaline earth metals heavier than beryllium all form saline hydrides. A well-known example is sodium hydride, which crystallizes in the NaCl motif. These species are insoluble in all solvents ...
Here are four easy methods including air drying, using silica gel, pressing, or even microwaving flowers to make them last all year long! You'll also find info on the best flowers to use in your ...
