Water is the reason  for life on earth. But water at unnecessary place in irrelevant form may become  the case of heavy loss for even big industrialists. This is because moisture  can help the growth of mold, yeast and fungi. Many big organizations face loss  as there product react with moisture and promote the growth of unnecessary  microorganism. When any product is stored, the chances are more that it will be  coming in contact with moisture. Mostly it comes in contact with moisture at  the time of transportation. So, as a safety measure, desiccant canisters are  the best solution. It increases the safety of the product by absorbing the  unnecessary moisture. It is mostly used for pharmaceutical purposes for the  packaging of tablets capsules and syrups. As it can absorb humidity very  quickly, this makes it one of the most demanded desiccants. It is absolutely  non- toxic desiccant which makes it more demanding as compared to any other.

 
These 
silica gel desiccant  canisters are very effective has they not only control moisture but  also control various activities as a result of moisture like the unwanted  growth of microorganisms in food items. We can say desiccant canisters are  basically small cylindrical containers which have to be filled with the active  agents. There are various other options which can be used in combination with  the desiccant canisters like silica gel or molecular sieves but among both,  silica gel is considered to be the best. According to the requirement there are  various types of canisters available but most of the companies make a standard  size ranging from 1/2 grams to 3 grams.
There are various  other types of desiccants like desiccant capsules, active- vials and many more.  Talking about capsules, it is a very similar product with that of canisters.  This is also available in different sizes and forms for different situations.  The capsules are made up of Amorphous Silicon dioxide, clay and aluminum oxide.  The advantage of using this product is that it has rapid moisture absorption  capacity and can dry the environment to up to zero percent humidity. It is  available in variety of shapes and is absolutely non-hazardous. It can function  as both structural and desiccant component. Vials is also available in two  styles flip flop and screw vials.
