Desiccants come in a variety of materials, shapes and sizes. There's everything from the well-known silica-gel, a little paper ball with "plastic" balls in, that you tend to find when you buy shoes and such items, to more industrial kinds such as the Absorbag or Absorpole, used to keep containers dry during freight. These tend to use other chemicals such as Calciumchloride - which is actually a constituent of sea-salt.
For the industrial-grade desiccants, there's companies like Absortech: absortech.com/. Silica-gel you can find on many places on the internet, for example at the desiccant-shop.com.
One can purchase a Desiccator at Amazon, AGM Container, eBay, Pronto, Next Tag, Lab Supply Outlaws, Scilabware, Duran-Group, and many over locations online.
Dispose of desiccants as non-combustible waste. When a large amount of desiccants are to be disposed of industrially, they should be treated as industrial waste.

Indicating silica gel is unique because it is treated chemically to make the transition possible from one color to another. It absorbs moisture and gradually becomes absolutely drenched in it. This characteristic of indicating silica gel makes it remarkable for absorbing moisture from the surrounding environment it is placed in. Their colors change when the Indicating desiccants are soaked with the surrounding moisture. Hence, indicating to the user that it is high time to replace or recharge the desiccants.
Desiccants are substances that have an affinity for water and will rapidly absorb any moisture from the atmosphere around it.
Yes, you do not leave them in the instrument. You actually may have to purchase a humidifier to keep it from drying out.
Silica gel can be reactivated by heating, as moisture adsorption does not change the substances. However, it is necessary to heat desiccants for packaging for a long time at a relatively low heat which usually costs more than actually purchasing new Silica Gel and often melts the glue which seals the sachets together.
I believe it is a condition that restricts the ligaments from keeping their bond to the bone. My girlfriend has it and her ligaments on her knee cannot form a strong bond to her bone.
Desiccants are particularly effective for water removal. Heat above 212°F usually does the trick, too.
Deliquescent solids, also called hygroscopic solids, are solids with a strong affinity for moisture. For instance, Calcium Chloride is deliquescent. Desiccants are a class of particularly deliquescent substances.
The two most common are Silica gel (found in new shoes and beef jerkey), and NaOH (sodium hydroxide), a strong base, found in disposable dehumidifiers.
There is both poisonous and safe desiccants. A common ingredient in some, for example, is Calciumchloride - a primary component of sea salt. You should not, however, digest either that type or silica gel.
For a correctly sealed item, 5 grams of silica gel are needed for every cubic foot of volume of the package. (170 grams per cubic meter.)
