Introduction to desiccant in pharma bottles

As a special medicine storage container, pharma bottles with desiccant cap are mainly used to protect humidity-sensitive medicines such as capsules and tablets from the effects of moisture. This kind of bottle is usually equipped with a desiccant inside to maintain the dry environment inside the bottle and ensure the quality and safety of the medicine. Silica gel and molecular sieves are two common desiccants.

Silica gel is a highly active adsorbent material that plays an important role in medicinal moisture-proof bottles with its unique physical and chemical properties. The microporous structure of silica gel gives it excellent hygroscopic properties and can effectively absorb and eliminate moisture in the air, thereby keeping the environment inside the bottle dry. At the same time, the chemical stability of silica gel prevents harmful chemical reactions from occurring when in contact with drugs, ensuring the safety of the drugs.

Molecular sieve is also a desiccant widely used in pharmaceutical moisture-proof bottles. Unlike silica gel, the mechanism of action of molecular sieves is mainly based on the selective adsorption performance of its crystal pore size arrangement. Molecular sieves can selectively adsorb moisture in the air based on pore size, while allowing other gas molecules to pass through, thereby maintaining a dry environment inside the bottle. In addition, the thermal resistance and chemical stability of molecular sieves also make them an ideal desiccant choice.

In practical applications, the desiccant in the pharma bottle will select an equal-proportion mixture of silica gel and molecular sieve according to the characteristics of the drug to achieve better moisture-proof effect. Both of them have unique physical and chemical properties in drug storage. Play an irreplaceable role.
