Molecular sieves, 3 Å

Molecular Sieves, 3 Å are synthetic zeolites composed of aluminosilicate frameworks with uniform pore sizes of approximately 3 angstroms. They are widely used in pharmaceutical and laboratory applications as desiccants, adsorbents, and drying agents.

🏭⚗️ Production
Molecular sieves are produced by hydrothermal synthesis of sodium aluminosilicate gels, followed by crystallization and activation at high temperatures. The 3 Å sieves are specifically processed to achieve precise pore sizes suitable for adsorption of small molecules such as water while excluding larger molecules.

🔬 Properties
Molecular sieves, 3 Å, are typically white, granular, or bead-like solids. They have a high surface area and uniform pore structure, allowing selective adsorption of molecules based on size. The material is thermally stable, chemically inert, and resistant to decomposition under normal laboratory and pharmaceutical conditions.

🧪 Applications
In pharmaceutical formulations, 3 Å molecular sieves are used to maintain low moisture levels in powders, solvents, and reactive chemicals, ensuring stability and shelf-life. In laboratory settings, they serve as desiccants in vacuum systems, gas drying, and sample preparation. They are also employed in the purification of reagents and in moisture-sensitive chemical reactions.

⚠️ Safety
Molecular sieves are generally considered safe when handled appropriately. Direct contact with skin and eyes should be avoided to prevent irritation. Protective equipment, such as gloves and goggles, should be used. They should be stored in airtight containers in a cool, dry place to prevent adsorption of ambient moisture and maintain effectiveness.
