Frequently Asked Questions (FAQs)

1. What are examples of desiccants?

Some of the most common desiccants include:. Silica gel (typically found in small “bead” form)Activated charcoal.Calcium chloride.Charcoal sulfate.Activated alumina.Montmorillonite clay.Molecular sieve.

2. What is a desiccator used for?

Desiccators are sealable enclosures containing desiccants used for preserving moisture-sensitive items. 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.

3. Are desiccants toxic?

Silica gel is usually non-toxic, but it is a choking hazard, especially for small children. Silica gel packets are frequently labeled with “Do not eat” because of the risk of choking.

4. What is the best desiccant?

Molecular sieve is the best desiccant based on technical performance characteristics. Its ability to adsorb moisture, in this case water vapor, is so pronounced that it can remove trapped H20 molecules from a fully saturated silica gel bead, which in turn changes the silica gel back to its original Cobalt blue color.
